Yang Fan was reviewing requests from various places when he noticed that his phone vibrated.
He put down his pen, turned on his vibrating phone, and saw the text message sent by the scammer.
He frowned a little, and Chu Chen wanted his help to find some rhenium metal.
He was a little confused. This thing is difficult to do. Where can he find it?
But he soon came to his senses. It was the end of Ming Dynasty here, and no one was trying to grab this thing from him.
He quickly searched Baidu to see where these things were produced.
Anyway, wherever there is a mine in modern times, it is open to the public. You can easily find it by following the map.
In modern times, Xinghe is well cared for by the superiors. The superiors call Xinghe a patriotic enterprise. They also provide a lot of policy care and preferential treatment. Yang Fan can't let go when the superiors need you.
After all, you have to be valuable to receive shelter and care.
Chu Chen didn't ask for it to be done. They knew how difficult it was to get this thing. When Chu Chen was asked to do it, it can be seen that it was more of a matter of having dates and not having dates.
Isn't this urgent? You have to try various channels.
If a big boss really contacted Yang Fan personally, or came to Yang Fan through Miss Lin, it would not be of this nature.
At least Yang Fan didn't get it, but he tried his best, and the bosses can understand. After all, this thing is too difficult to get, isn't it?
Yang Fan searched carefully.
Rhenium ores are mainly distributed in America and Europe. The amount of associated rhenium resources in global rhenium-containing deposits is estimated to be more than 33,000 tons. The actual proven amount is more than 2,600 tons.
Among them, Chile has the most abundant proven rhenium resources, with 1,300 tons, accounting for half of the world's total.
Followed by the United States (390 tons), Russia (310 tons), Kazakhstan (190 tons), Armenia (95 tons), Peru (45 tons) and Canada (32 tons).
About 80% of the world's rhenium is used in the production of aviation engines, which is of great significance in military and strategic terms.
After COMAC’s first flight on September 19, global rhenium prices skyrocketed, and supply suddenly exceeded demand.
Because the engine-turbine blades are made of high-temperature alloys containing 3% to 6% rhenium.
In the next twenty years, the total demand for rhenium-containing superalloys for domestically produced aviation engines will exceed 2,000 tons. The average annual demand will exceed 100 tons.
Sadly, the current annual production in the world is only more than 40 tons. Most of them are associated with other metal minerals such as molybdenum, copper, lead, zinc, platinum, niobium, etc. The extraction technology is extremely difficult, and it is more difficult to obtain than diamonds.
.
Domestic rhenium mines are mainly distributed in Shaanxi, Heilongjiang, Henan, Hunan, Hubei, Liaoning, Guangdong, Guizhou and Jiangsu provinces. The rhenium mine reserves in these areas account for about 90% of the country's total rhenium reserves.
Specifically, among the top three domestic rhenium ore reserves, Shaanxi has the largest rhenium reserves, accounting for 44.3% of the country's total. Heilongjiang accounts for 31.6%. Henan accounts for 12.7%.
There was nothing that could be done for a while abroad, but looking at China, Yang Fan had an idea.
Chile has the largest reserves, but is also the furthest away.
Yang Fan sent a fleet of three cruisers last year to explore the American continent.
Looking at the time now, we should have arrived in South America. We can send a telegram and ask them to go to the rhenium mine in Chile to collect some ore.
Yang Fan had no way to refine it because rhenium was found in other mines. Yang Fan could only get the ore powder back and let Chu Chen and the others find a way to extract it themselves.
Shaanxi and Heilongjiang in China are both within reach of Yang Fan.
Heilongjiang is completely under his control. As for Shaanxi, due to immigration reasons, although the two divisions of the Uzbek Army have returned to Qinghai, the Ordos militia, with 20,000 to 30,000 people, continues to relocate the poor without food there.
.
Just send them a telegram directly. These militiamen are also led by my hometown servant. They all have radio stations.
Yang Fan also understood the urgency of Chu Chen and the others.
At present, the world's rhenium resources are in a monopoly. The world's largest rhenium producer is Meiliguo Molybdenum Metal Company.
It monopolizes most of the rhenium production in Chile, Mexico and Kazakhstan in the form of long-term contracts. It also blocks panda materials and technology all year round, controlling the global sales market.
Fortunately, in 2010, Lianshi Company discovered rhenium in the mines in the molybdenum mining area in Luonan, Shaanxi.
The mine has 128,450 tons of molybdenum reserves and 176.11 tons of associated rhenium. The reserves account for approximately 7% of the world's proven reserves, ranking fifth in the world, breaking the global resource monopoly.
Yang Fan quickly opened the map and found that there happened to be a militia group not far from there. He just asked them to dig some ore first, teleport there first, and let the scammer give it to Chu Chen to test and see the grade first. If it meets the requirements, you can continue
Provide them with.
After all, 3,000 steam trucks with a load of 6 tons were mobilized for this immigration. A thousand trucks can be mobilized to transport 6,000 tons of molybdenum ore back first.
Although I don’t know the grade, molybdenum ore is not cheap and is also a rare metal. Just sell it to Chu Chen and the others as molybdenum ore. As for how much rhenium is in it, I don’t care. I don’t make money from this anyway.
Six thousand tons of molybdenum ore, based on a grade of one thousandth, can contain six tons of molybdenum metal. Calculated based on the associated rhenium ore, which is about one part seven hundred and twenty-two, it should be more than 8 kilograms.
Eight kilograms is a lot. This thing is industrial MSG, just use a little.
The annual national output of Dannili is just over seven tons.
Yang Fan checked and found that molybdenum ore is easy to purify, just like gold.
Re-select first. It will crush the vibration and settle in the lower layer.
For remagnetization, just use a magnet or a magnetic bar. Yang Fan has the equipment, so it’s not difficult.
The last step is electrical selection, which is not too difficult. After all, the academy can already make lacquer-insulated enameled wires.
A coil generator can be used, and it is not a problem to get a steam engine to drive it, or an electric option.
In this way, 50% grade concentrate powder can be selected from molybdenum ore.
If it is molybdenum ore concentrate powder, it will contain more rhenium ore.
Six thousand tons of concentrated ore powder transported at one time can purify more than 8 tons of rhenium ore. Last year, the national annual output of Dameili was only seven tons. (They deliberately control the output. They only have enough for themselves.) It is useless for Yang Fan to ask for this thing.
, just dig hard enough.
It's just a bit labor-intensive, and mining requires a lot of people, especially under the rudimentary technical conditions of the late Ming Dynasty.
Fortunately, Yang Fan already has tunnel support technology, explosive blasting technology, steam bulldozers, excavators, loaders, steam trucks, etc.
In fact, people are not a problem. There are still many refugees in the southern and central areas of Shaanxi. Yang Fan did not want to provoke the court and cause appalling behavior, so he did not dare to move around Xi'an.
Now it's just right. Yang Fan had been coveting the population resources of Hanzhong and Guanzhong. Now he has an opportunity. If he can't take it away, he can use it to mine for himself.
Shangluo County is just east of Xi'an. It happens to drive all the landless people in the core area to mine. One is to give them a way to survive and avoid starving to death. The other is to stabilize the place and prevent them from running away to become thieves.
