Chapter 152: Finding the Bottom (Medium Cup)
Jiang Miao is not too worried about what happened at the headquarters. After all, Hailufeng Company is no longer in the start-up stage a year ago.
With all the systems in place and the presence of his brother-in-law, sister, Shuya and others, he doesn't have to worry about big problems.
As for the third thing, the group of people who tried to steal the secrets of Hailufeng Company were a group of Annan people who came from the border of Guangxi Province.
Judging from the details sent by Jiang Haibo, these guys used underground channels to cut sugar cane in Guizhou Province, and then ran from Guizhou Province to Shanmei through township roads.
Because of this incident, the local people in Shantou and Meizhou have specially reported it to the superiors. It is estimated that in the next period of time, the Annan people in the south of Guangxi Province who want to come to cut sugar cane will be in bad luck.
Jiang Miao also took the time to investigate the motivated companies and forces in the Annan area through the Internet. In less than two hours, he found these guys.
Mainly because in the investigation report, there was a satellite phone that those guys carried with them. Jiang Miao used the number of this satellite phone to reversely locate the other party's location.
It's easy to do if you have a location.
"The South Vietnam Group?" His eyes were full of coldness: "I don't know whether to live or die."
Then Jiang Miao followed the network cable and opened the Nanyue Group's factory internal network.
Seeing the other party's fishmeal factory that was half-stopped, he skipped those fishmeal factories and targeted the other party's factory that was currently producing.
For example, the pangasius fillet production line.
He used the mobile phone carried by the operator to adjust the electronic scale in the additive dispensing room and secretly increased it to 2 times, but the surface display still showed the original number.
In the process of processing fish fillets, three types of additives are generally used, namely water-retaining agents, antioxidants, and preservatives.
Among them, the antioxidant is mainly vitamin C, and the preservative is potassium sorbate. Excessive use of these two things will not cause any major problems.
However, water-retaining agents, usually sodium tripolyphosphate, sodium hexametaphosphate, etc., can be used in appropriate amounts to maintain the moisture and taste of fish fillets, making them less likely to lose water and dry out during storage and cooking.
If too much phosphate is added, the phosphorus content in the fish fillet will be too high, which will affect the body's absorption of calcium, lead to disorders of calcium and phosphorus metabolism, and increase the risk of osteoporosis, fractures and other diseases.
Of course, twice is actually not high, and it doesn’t matter if you eat one or two meals occasionally.
Moreover, Jiang Miao has no intention of letting these products flow to the market. As soon as the Nanyue Group's problematic fish fillets are produced and exported, he will report them to Seris and América Customs through the Internet.
Because the main export markets for Nanyue Group's fish fillet products are these two places.
But this alone is not enough.
Jiang Miao followed the same example and entered the Nanyue Group's factory with an annual output of 800,000 tons of feed. He unexpectedly discovered that the equipment automation level of this factory was quite good. There were even several advanced batching machines that could mix feed raw materials. Spray in a certain amount of trace elements and trace ingredients.
The parameters of this equipment are set through the computer.
He kindly studied the formula for the other party, specifically for their main products of pangasius feed, vannamei shrimp feed, and tilapia feed.
After much deliberation, Jiang Miao chose white shrimp, mainly because the economic value of this aquatic product is relatively high, and compared to the durable pangasius and tilapia, white shrimp is too easy to die.
In addition, the pangasius feed of Nanyue Group is mostly digested internally, while the white shrimp feed is mainly exported to local farmers. After using their "feed", farmers who have lost their production in large areas will definitely turn to Nanyue Group trouble.
He just casually adjusted the injection amount parameters of several trace elements, so that the new formula feed could cause the oxygen in the white shrimp's body to be unable to combine with hemoglobin, and thus die of hypoxia.
Get it all done.
March 14th arrived unknowingly, and three days had passed since Jiang Miao arrived in Zhelimu City.
His inspection of the branch is almost over, and he has also adjusted the management of the branch, and transferred some of the management that may have problems back to the headquarters, or directly dismissed them.
But his visit to the Monan branch is not over yet.
This time, Jiang Miao did not let Lu Weibin and others accompany him. Instead, he took Li Zixuan, Ke Yong and more than a dozen people to drive four pickup trucks of the branch to "tour the mountains and rivers" in Jiayuan County.
In fact, it was Jiang Miao who was looking for mineral veins.
Hailufeng Company actually has the relevant procedures and qualifications for mining. This is a legal procedure obtained through the relationship with the Feed Association.
However, Jiang Miao does not plan to mine related minerals immediately, nor does he plan to let Hailufeng Company mine itself. Instead, he will set up a subsidiary.
The reason why we want to engage in mining business is mainly for the future.
As the international situation has become increasingly severe in recent years, Jiang Miao must prepare for a rainy day.
Although agriculture and mining may seem unrelated, in fact, the two are very closely related, such as the three major fertilizer raw materials of nitrogen, phosphorus and potassium, as well as a large number of trace element fertilizer raw materials, many of which need to be solved through mining.
Nitrogen fertilizer can be synthesized from coal or natural gas, using air.
But potash and phosphate fertilizers require the mining of minerals, especially phosphate fertilizers. China currently mines hundreds of millions of tons of phosphate ore every year, producing about 40% of the world's phosphate fertilizers. However, domestic phosphate ore reserves only have three billion tons left, and Many of them are low-grade ore veins, and the cost of refining them is too high.
But it won’t work if we don’t produce.
In addition, there are copper ore, manganese ore, cobalt ore, chromium ore, and platinum group, which are all very scarce mineral resources in the country.
The most dangerous among them is the phosphate rock.
The main reason is that after phosphate rock is made into fertilizer, it is easily dissolved by water and carried into rivers and lakes, and finally flows into the sea. This process is almost irreversible.
Of course, if all the discharged agricultural water and domestic sewage are collected regardless of cost, the phosphorus in them can indeed be extracted again.
But the problem is that the cost of doing this is hundreds of times that of phosphorus produced from phosphate rock, which will increase the price of phosphate fertilizer hundreds of times.
If the price of phosphate fertilizer increases hundreds of times, the consequences will be disastrous.
Taking wheat as an example, one acre requires about 4 kilograms of phosphate fertilizer, and each kilogram is about 0.9 yuan. That is, the cost of phosphate fertilizer per acre is 3.6 yuan. If the price of phosphate fertilizer increases 50 times, the phosphate fertilizer input cost per mu of wheat will become 360 yuan. Yuan.
You should know that the average domestic wheat yield per mu is only about 450 kilograms, and the average cost of wheat per kilogram will increase by 0.8 yuan.
Domestic wheat purchases increased from 2.34 yuan per kilogram in 2023 to 2.36 yuan per kilogram in 2024, and then to 2.38 yuan per kilogram last year, with prices increasing by only 0.02 yuan per year.
If the purchase price of wheat is suddenly increased by 0.8 yuan, the prices of other daily necessities will also rise accordingly.
The three major chemical fertilizers are indispensable supplements in the growth process of plants. Without phosphorus fertilizer, relying solely on the phosphorus element in the soil is completely insufficient, which will lead to a decrease in the production of grains, vegetables and fruits. The cold resistance is reduced and the disease resistance is reduced.
Some people may think that Jiang Miao is unfounded.
Domestic phosphate rock reserves can be used for at least thirty years. Maybe by then, the technology to extract phosphorus from natural water bodies has been solved and can be produced cheaply.
However, judging from the actual situation, the production cost of refining phosphorus from seawater can never be lower than the cost of refining phosphate rock. The answer lies in the content.
Morocco's high-grade phosphate rock has an average phosphorus content (calculated as phosphorus pentoxide) of 33 to 34%, while the domestic average content is around 16%.
The phosphorus content of seawater is 0.07 mg per liter.
The content of the two is very different. Unless controllable nuclear fusion can reduce the electricity bill to 0.01 yuan per degree, otherwise, if phosphorus is extracted from seawater, it is better to just wash it off and sleep!
Even if the country still has the snowy plateau, the last mineral reserve, the mining and refining costs of the three billion tons of phosphate ore will become increasingly high.
Once America discovers that food weapons are ineffective, you will see whether they will take action to disrupt mineral mining in other areas of the country.
And now if the country wants to achieve complete self-sufficiency in grain, oil, feed, and sugar, fertilizer production capacity cannot be reduced.
Therefore, it is necessary to find high-grade phosphate rock domestically or develop efficient phosphorus extraction technology.
These two directions are things Jiang Miao can do.
As for the high-grade, easy-to-mine phosphate rock, he actually didn’t have much hope. After all, the depth of underground mining exploration in many areas in the country has reached four to five hundred meters. Even if there is a fish that slips through the net, it is equivalent to Try your luck. He focused on ultra-low-grade junk veins.
In fact, Jiang Miao has already investigated the phosphate rock situation in Zhelim City. The phosphate rock type here is mainly magmatic apatite. The reserves of this type of phosphate rock account for 7% of the total domestic reserves and are mostly distributed. in the northern region.
Under normal circumstances, the grade of this type of phosphate rock is low, usually less than 10%, or only 2% to 3%, and has no industrial mining value.
In addition, other minerals are also associated with phosphorus, but the content is generally very low.
For example, the magnetite in front of us at a depth of 50 to 80 meters below the desert has an average phosphorus content of about 0.63%. The total amount of magnetite contained in this magnetite is only about 110,000 tons. Only when all of it is mined can we Refined 693 tons of phosphorus pentoxide.
This kind of small iron ore has no mining value at all.
That night, Jiang Miao and his party rested all night in Zhelimu City.
The next day, at dawn, the motorcade headed north along Highway 304 to Servant County in the north.
When passing by the Hairihan Forest Farm, Jiang Miao stopped. He found a large area of very shallowly buried magmatic apatite in the nearby mountains. The average content of phosphorus pentoxide was 2.3~ 3.1%.
"Let's check it out nearby."
Read the error-free version at 69 Book Bar! 6=9+Book_Bar debuts this novel.
Naturally, Ke Yong and others had no objection to Jiang Miao's instructions.
After driving slowly for more than three hours along several township roads or dirt roads, Jiang Miao took a rough look at this magmatic apatite vein.
The magmatic rock-type apatite in this area is distributed in flakes, which is one of the characteristics of magmatic rock mineralization. Its mining area is 7.9 kilometers to 11.6 kilometers wide, 47 to 49 kilometers long, and 12 to 15 meters thick. It is buried The depth is 5 to 20 meters, and some areas can be mined in the open.
The average phosphorus content of the magmatic apatite here is 2.3 to 3.1%, and a small part can reach 7.2%, but the proportion is very small.
The mining cost of this kind of mineral vein is too high. It is estimated that the local mineral exploration department has already inspected it and feels that it has no industrial value.
However, the total amount of magmatic apatite minerals here is very huge, a full 5 billion cubic meters, or almost 15 billion tons of ore.
Calculated based on an average phosphorus pentoxide content of 2.7%, it contains almost 405 million tons of phosphorus pentoxide.
If traditional techniques are used for refining, the mining and refining companies will lose so much money that they will lose their pants.
In fact, magmatic rocks in the northern region generally contain apatite, but the content is too low to have industrial value.
Similar to the magmatic apatite under Jiang Miao's feet at this time, there must be at least hundreds of billions of tons of reserves in the entire north.
So how does Jiang Miao solve the problem of mining costs?
The answer lies in biomining technology.
The so-called biomining utilizes the special taste of bacteria and fungi for certain elements to enrich specific elements from minerals and water.
For example, leguminous root nodules essentially solidify nitrogen from the air through bacteria.
There are also many current poor copper mines that will also be mined using biomining technology.
The advantages of biomining are low energy consumption, environmental friendliness, and the ability to process lean ores.
The disadvantage is that the efficiency is relatively low, and microorganisms require specific culture reaction tanks. In addition, there are relatively few bacteria and fungi that can efficiently enrich specific elements, and it is also difficult to cultivate artificially.
And this is exactly what Jiang Miao is good at.
His mining plan is to drill wells and inject a refined liquid containing specific bacteria and nutrient solutions, allowing the bacteria to multiply wildly in the surrounding strata, enriching the phosphorus in the rock formations, and then regularly extracting the refined liquid and replenishing the nutrient solution at the same time.
The well will be abandoned until the phosphorus content in the surrounding underground rock formations is absorbed to only about 0.3%.
Jiang Miao has tried more than a dozen kinds of bacteria in the laboratory.
At present, only three types of bacteria have been selected as the focus of research, namely: Rhodospirillum crimsonii, planktonic bacteria, and nitrifying bacteria.
The reason why these three bacteria were chosen is naturally that they are not pathogenic bacteria. Even if they are infected, there will not be much risk.
Many other species of Chromobacteria, Bereriatoella, Acinetobacter, Aeromonas, and Pseudomonas can cause fatal infections in humans and animals, so they must be eliminated.
Jiang Miao is more optimistic about planktonic bacteria.
Planktonic bacteria are mainly distributed in organic matter-rich flowing fresh water such as polluted rivers, filter tanks and activated sludge, and are extremely aerobic.
It has the function of decomposing phosphorus and potassium. It can also activate the medium elements of silicon, calcium and magnesium in the soil, increase the supply of iron, manganese, copper, zinc, molybdenum and boron, improve or extend the fertilizer efficiency, reduce the amount of chemical fertilizers, improve crop stress resistance, prevent or Reduce disease, and during its growth and reproduction process, it can also produce organic acids, amino acids, polysaccharides, hormones and other substances that are beneficial to plant absorption and utilization.
Therefore, if planktonic bacteria are injected into groundwater wells, serious pollution can be avoided. When they are needed to enrich phosphorus, air is introduced into the well through an air pump. If they are no longer needed, the nutrient solution is stopped and the wellhead is closed. , which can suffocate floating jersey bacteria underground.
In addition to enriching phosphorus, planktonic jersey bacteria can also enrich potassium, which is equivalent to eating two fish for one.
Unlike the phosphorus and potassium extracted by traditional industrial methods, the phosphorus and potassium extracted by phytoplankton bacteria is actually a kind of organic fertilizer. It only needs to adjust the proportion of phosphorus and potassium, and it can be sold directly as organic fertilizer, which saves another process.
The only trouble now is that cultivating planktonic bacteria is more troublesome.
The isolation and purification of this bacterium is difficult. A common solution is to use low nutrition for enrichment culture. Generally, laboratories often use liquid preservation methods. In addition, simple preservation methods, liquid nitrogen ultra-low temperature preservation methods, etc. can also be used to preserve them.
Fortunately, Jiang Miao can know the various characteristics of the planktonic bacteria through their genetic sequences.
He used agar as a culture medium, added some specific ingredients, and then planted the planktonic bacteria strains and allowed them to multiply for 3 days. Finally, he directly used a freeze-drying process to create a strain block.
This thing can be stored for a long time in a sealed pure nitrogen environment, which is convenient for large-scale production and release of planktonic strains.
In the process of use, the bacteria are thrown into the water, then specific nutrient powder is added, and air is introduced. In the summer when the temperature is relatively high, it can reproduce quickly in a few hours. Finally, the planktonic bacteria extract is injected into the well. Just inside.
Jiang Miao conducted a simulation experiment and found that it only takes about 10 days. With the support of a specific nutrient solution, the planktonic bacteria can absorb phosphorus elements in a radius of 3 to 5 meters around, so that the planktonic bacteria in the extracted solution have multiplied to the limit. By this time You can pump out the mineral fluid.
After the mineral-containing bacteria liquid is extracted, it is injected into the separation pool, and ultrasonic waves are used to expel the planktonic bacteria to local areas of the pool.
This is because Jiang Miao studied the genes and body structure of phytoplankton bacteria and found that they are very sensitive to and disgusted with specific ultrasonic waves. As long as they continuously emit ultrasonic waves of this special frequency on the side of the water body, they can actively stay away and achieve enrichment again. .
The reason for this is to reduce the waste of water resources, so that 95% of the water in the mineral-containing bacterial solution can be injected into the well again.
The highly enriched mineral-containing bacteria liquid remaining can be evaporated naturally or heated to obtain crystals rich in phosphorus, potassium and organic matter.
Using this set of processes, if it can be rolled out on a large scale, it will only cost about 870 yuan per ton of pure phosphorus (equivalent to 2.29 tons of phosphorus pentoxide) on average.
At the same time, 50 to 600 kilograms of potassium (equivalent to 95 to 1140 kilograms of potassium chloride) can be extracted, depending on the potassium content in the rock formation.
This cost is similar to that of phosphorus pentoxide produced from phosphate rock in China. The current domestic production cost of phosphorus pentoxide per ton is about 400 yuan.
Moreover, the phytoplankton biological phosphorus and potassium mining technology causes very little environmental pollution and does not consume much water resources. It does not require large-scale blasting and excavation, nor does it require too many mining and smelting equipment.
It is these advantages that make the overall cost of this technology almost the same as that of traditional phosphate rock refining methods.
The emergence of this technology means that the domestic industrial reserves of phosphate rock will increase by hundreds of billions of tons. Even if the content of these phosphate rocks is only 2 to 3%, billions of tons of pure phosphorus can be extracted.
If the country consumes 20 million tons of pure phosphorus every year, these billions of tons of pure phosphorus can support domestic demand for hundreds of years.
However, Jiang Miao estimates that this technology will most likely only be used as a reserve technology, because China has been trying to reduce the scale of local phosphate mining in recent years and find ways to solve the phosphate supply problem through outsourcing.
The government is very likely to approve a few companies to use this technology, and then limit the scale to a certain range. This can ensure that there is a corresponding technical talent reserve and does not require large-scale mining. If the international environment suddenly deteriorates, We can use the reserve talents of these companies to quickly expand production.
