Chapter 946 This guy is poisonous
"Really? That's great. Mr. Gao, what's the solution?"
Gao Zhendong stood up and began to draw pictures on the blackboard. That was the core process of another method.
He said while drawing: "We use amalgam electrolysis method! This method is the most friendly to Qianshan."
Mergam is a very interesting metal. It is the most famous feature of being liquid at room temperature. In addition, it can generate X-afford with many metals, such as gold. It is said that mercury eats gold, which is what it comes from, and it also contains gallium.
When the comrades from Qianshan heard this, they knew why Gao Zhendong said that this method was the most friendly to Qianshan.
There is mercury in Qianshan, and it is not a little bit. It is a large mercury mine. Later, it even became a special mineral zone like the several special zones of Meishan - Wanya Special Zone.
Wanya Mercury Mine was later completely hollowed out, but it has not been around for now.
In Gao Zhendong's previous life, a considerable proportion of the mercury mines here were used to repay the debts of the Russians, but on this line, there were not so many debts to be paid by minerals, and there were a lot more things that could be done.
The amalgam electrolysis method actually appeared in Europe in 1955, but it was not popular. It was really popularized in the 1960s, and we only started using it in the 1970s.
The basic principle is to use mercury cathode to electrolyze the gallium-containing solution, such as the Bayer method mother liquor. The electrolytic gallium will generate gallium amalgam with mercury, which will directly separate gallium amalgam and other mother liquors. The gallium amalgam enters the gallium-making process, and this mother liquor enters the original process of making alumina.
As Gao Zhendong's flow chart gradually became clear, the comrades in Qianshan knew why Gao Zhendong recommended the amalgam electrolysis method. In addition to Qianshan also producing mercury, this method is really suitable for the current situation in Qianshan. "Hey, the mercury here can be recycled." "This seems much simpler, the equipment used is not complicated, and the investment is very small." "General Gong Gong is so awesome. The process equipment is simple and the investment is small, which is really suitable for us."
"This method can even extract other metals, genius!!"
"..."
Yes, in addition to refining gallium, amalgam electrolysis can also refine vanadium!
As a type of refractory metal, vanadium is also a commonly used "alloy vitamin" and can be used to improve the performance of alloys. Although the amount is not large, the effect is not small.
Although this thing doesn't sound very famous, it is actually one of the advantageous metals in my country later. The main reason is similar to gallium - this thing is also accompanied by, and the content is not high, so it cannot be specifically refined. It can only be obtained from the production of other metals, such as electrolytic aluminum.
The amalgam electrolysis method taken out by Gao Zhendong after perfection is directly filtered with the mother liquor after separation of gallium amalgam, and vanadium slag containing vanadium can be obtained for refining vanadium.
Gao Zhendong listened to his comrades and smiled: "Comrades may have seen that the products of this process are diverse. Of course, mercury is toxic. You should pay attention to this issue during the production process. As for the source of mercury, I think Qianshan does not need to worry about it." Although mercury can be recycled, it will definitely be depleted in the process, and a stable source of mercury is equally important.
He explained the entire process in detail to the flow chart and spent a lot of time. The comrades from the aluminum factory listened and recorded while nodding. This thing is good and must be used even if it is toxic. Just take good protection.
In fact, after the 1960s, the whole world was using this method until the ion exchange method appeared.
Gao Zhendong smiled and said, "In fact, there is another way, which is more economical and safer than amalgam electrolysis method, and does not need to add any other reagents to the mother liquor for producing alumina, which will not have any impact on the production of alumina. However, this method requires some very important raw materials and has not been developed yet, so I can only feel wronged for the time being and use the amalgam electrolysis method first. Moreover, if you want to obtain vanadium, you still need other processes."
There are other experts? The comrades from the aluminum factory were shocked.
What is the treasure of the seventeenth Ministry of Machine Building? This is what I have seen. If there are traces to both lime milk method and amalgam electrolysis method, then I have never heard of this new method proposed by Chief Engineer Gao. "What do you need for Chief Engineer Gao?" The comrades in the aluminum factory couldn't help it. To be honest, even if this method is available at this stage, it is not as useful as amalgam electrolysis in their eyes because there are fewer products.
"Chemical resin, I'm going to ask comrades who are engaged in chemical engineering to do this later. There is only theory now, but there is no actual product yet. You won't consider this method for the time being."
Chemical resin directly exchanges the gallium ions in the solution. Moreover, this method can not only be used for gallium, but also for different chelating resins, not just metal ions, but is a very promising technology.
This is why Gao Zhendong is very interested in this technology. This thing is very useful.
In fact, in some water purifiers in later generations, in addition to the RO reverse osmosis membrane, this thing was also used, which is a very useful thing.
Gao Zhendong's words were filled with big things invisibly, and the comrades in Qianshan were impressed by them. "Mr. Gao, we will organize our forces to study the specific implementation process of the amalgam electrolysis method." The director of the aluminum factory was very excited and didn't even have to bring the words to the department. The problem was solved by General Gao.
There are aluminum, gallium, vanadium, and these little days are beautiful. What is this called? This is called having a woman, having a family and having food! Live together!
It seemed as if I felt that my Lenovo was really unreliable, and the manager of the aluminum factory laughed at himself. Indeed, Lenovo is not very reliable most of the time.
Gao Zhendong did not forget to send his last assist: "You report this matter to the department to the department, and the department will approve it quickly."
Comrade Qianshan who accompanied him also smiled and said, "General Engineer Gao, you cannot just let the department work. Although our province is not rich, we still have to participate in this kind of event, and we don't have much strength. Here, I guarantee to the comrades of Qianshan Aluminum Factory that no matter how large the funds you need, the local area will match 15% of the funds."
15% sounds not much, but it is the greatest effort of Qianshan local area, which well reflects their attention to this matter.
The comrades in Qianshan know very well that they cannot rely on the above to find solutions to such things. The local area will not express it. Who knows if there will be such good things in the future?
He didn't know whether the weight of gallium and vanadium was important, but the top experts in the department said that it was important, so there was no problem.
As for how to match funds, there are some methods. Without funds, materials, land occupation, and manpower can always be squeezed out. In fact, many national projects later matched funds in local areas with economic difficulties by similar means.
This kind of good thing makes the comrades at Qianshan Aluminum Factory feel so happy that they are about to faint. Good things happen every year, and this year they will come to my house. "Thanks to the leaders of the Ministry and the Provincial Department for their attention and support. Our Qianshan Aluminum Factory ensures that we must complete the relevant work with quality and quantity, and do not waste a penny of the country."
When we were about to leave Qianshan Aluminum Factory, Gao Zhendong saw something, which was a special map hanging on the wall of the aluminum factory conference room.
The newest ⊥Xiao⊥Speak⊥Send⊥Six⊥9⊥Book⊥⊥⊥⊥Back⊥⊥⊥⊥!
As you are in the reception, you know that you have whatever you want, and you wish you could show off all the little things. So this thing is strictly related to the aluminum factory, but it is not directly related, so they also hung up.
Hey, I'm familiar with this thing. Although it is only familiar with bauxite, that's enough.
It is a proven distribution map of bauxite in Qianshan area. In fact, it has far less relationship with the aluminum factory than the ground survey. After all, the aluminum factory only needs to use bauxite, but as a comrade in the mine search, there are much more things to consider in this regard.
Gao Zhendong stopped and looked carefully for a long time while pretending to behave, and even didn't let go of the geological map hanging next to him.
If you don’t pretend, otherwise it will be too terrifying and will scare your comrades.
Seeing him stopping and watching, the other comrades also stopped. What did Chief Engineer Gao find?
To this day, the comrades in the aluminum factory have no doubts that Mr. Gao is not familiar with aluminum. They know it very well, and they have a lot of it.
Although he didn't know what attracted Mr. Gao, he was willing to stop and watch and express his interest, that was a good thing, maybe...
Sure enough, Gao Zhendong did not disappoint them, and said something that might surprise the comrades who were doing territorial investigation, although they were not on the scene now.
"I suggest that you ask comrades who are in the exploration to go to these places to see, and you should get something."
After saying that, Gao Zhendong clicked on several places on the map.
The comrades next to them were surprised and happy. Can you tell this? Just looking at the bauxite distribution map and geological map for a while, this is not even a very detailed map, it is very sketchy. How much information can a picture hanging on the wall have? Even if Qianshan is not large, it still cannot be fully displayed.
But Chief Engineer Gao can see the tricks and directly point out where there may be mines.
From Chongyi to Qianyang, there is a bauxite belt. Although it is a mine belt, it does not mean that all the places on a belt are mined value, and the place at the east point of Gaozhen happens to be an undisclosed area.
Although I don’t know how Gao Zhendong confirmed that there are mines in these places, his words have undoubtedly received the highest level of attention from the comrades. We must ask the comrades who are in the exploration to take a look immediately.
If it is true, then Chief Engineer Gao’s fingers have saved so much money, time and manpower.
It must be true. It may not be clear where Gao Zhendong's other mines are distributed. After all, he was just a military fan in his previous life and did not study related majors. However, he happened to know very clearly about the bauxite distribution in Qianshan, which is also the only resource point he knew clearly.
I watched it at the homes of my elders in my previous life.
