September in the north of the border has a slightly moist southeast wind.

Huang Xiuyuan picked up the telescope. He was at the Kulun Banner in Tongliao at this time, which was the eastern part of Mongolian District and the prairie that foreigners remembered.

The sky is vast and the wilderness is vast. The scenery of cattle and sheep is visible when the wind blows the grass. This fixed impression is not the true color of the Kulun Banner.

The convoy heads north from the urban area of ​​Kulun Banner, follows Provincial Highway 451, and once you pass Harererigegacha, you can see dilute grasslands, mobile sand dunes and semi-sandy land on both sides of the highway.

After Huang Xiuyuan held a meeting in Peking, he did not rush back to Lingnan, but came to Tongliao.

On one side of the road, on the edge of the sand, a row of container houses were built, with signs of Fengmin Agriculture in Blue Era.

Next to the temporary site, there is also a factory under construction, which is a breeding farm and forage processing plant planned by Fengmin Agriculture.

And the Blue Age came here to mine mineral resources.

An element refining truck transformed by a desalination truck and a matching dirt truck are running quickly.

Soil, sandy soil, and rocks contain most elements, but it is just a matter of the content.

For example, in the Coulon Desert at this time, after testing, the gold content in the soil was about 7.6 to 8.2 parts per billion, the rhenium content was about 3.4 to 3.8 parts per billion, and the iridium content was 2.4 to 2.5 parts per billion.

But in fact, there will be deviations during the refining process because the distinction between various elements is never uniform.

The Korqin Sandland with an area of ​​42,300 square kilometers can obtain huge resources by refining the surface soil.

Dongfeng Mengshi stopped in an ordinary piece of sand, which was a relatively low-lying piece of sand. Judging from the remaining soil and sand, it should have been one of the ancient riverbeds before.

"Mr. Huang, this area is a gold-bismuth-lead composite ore vein with a length of 17.6 kilometers, a width of 34-247 meters, and a depth of 3-11 meters." Song Shijia, who is in charge of mining business, said, pointing to the sand under his feet.

Huang Xiuyuan squatted down and grabbed a handful of sand and soil: "How much is the value?"

"Each ton is about 0.08 to 0.12, and the reserves are about 1.2 tons. The upstream here used to be a small gold mine, and those valuable mines have been mined completely."

Huang Xiuyuan was not surprised by this.

Domestic gold mines are now mainly poor and gold mines with mining value, with gold content usually around 0.5 to 3 grams per ton.

The gold content is less than 0.5 and usually does not have mining value, and the mining cost will be higher than the gold value.

Just the technology of Suiren Company can mine this super-poor mine and make profits.

Using six-cone ball oxygen for refining is not only close to 100% refining efficiency, but also very energy-saving and environmentally friendly. The comprehensive refining cost of this super-poverty mine is about 20 to 30 yuan per gram.

If it is soil refining, the cost is around 90-110 yuan per gram.

The current price of gold is more than 200 yuan. Even if it is purchased by the central bank (30% off), one gram is around 160 to 170 yuan.

Therefore, the Blue Age has eaten a large number of waste mines, which are cheap and have certain infrastructure.

Of course, the waste ore acquired by the Blue Age are all minerals containing rare resources, such as gold ore, silver ore, platinum ore, as well as multi-element composite ore containing rhenium, iridium, rhodium, palladium, tungsten, tellurium, ruthenium, and osmium.

For example, among the three scrap copper mines contracted in Shandong Province, the rhenium content in the rock is only about 0.0008 to 0.0011%, and the mass of waste slag and stone is about 8.5 to 9.6 million tons, and it is expected to be refined about 68 to 105.6 tons.

You should know that the global exploitable reserves of rhenium are only about 2,500 tons, including 1,300 tons of Chile, 390 tons of the United States, 310 tons of Lucia, 190 tons of Kazakhstan, 95 tons of Armenia, 45 tons of Peru, 32 tons of Maple Leaf Country, and 91 tons of other regions.

Although the rhenium ore in China retains a reserve of 237 tons, they are all poor ore with very poor grades. The difficulty of mining and refining is very different than that of high-grade ore abroad.

At present, among the various waste ore, tailings and super-poor mines acquired and contracted by Blue Age nationwide, the proven rhenium reserves are around 736 to 982 tons.

This quantity seems to be in short supply of rhenium ore in China.

In fact, if there was no mining technology of Suiren Company, these would not have mining value at all. Any mining company would dare to mine such an ultra-poor mine, which would probably have lost its pants.

Because the main purpose of rhenium metal is to make high-temperature resistant materials, such as blades of jet engines.

The largest producer is Chile and the largest consumer is the United States, so the price is seriously underestimated. The current market price is only 37 to 45 yuan per gram.

For an element that is less rare than gold, the price is only about one-eighth of that of gold. It would be strange if there is no trick.

In fact, the same is true for domestic rare earth resources. The export price is simply bargaining. Later, the official integrated the rare earth industry to curb this phenomenon of low-selling resources.

And those small countries have no right to speak in international trade and can only be slaughtered by others. The price of rhenium metal is a reflection.

For these rare resources mined and extracted, Huang Xiuyuan’s plan is to serve as a strategic reserve. Except for some of them used by themselves and sold to some domestic enterprises in need, the remaining production volume is used as a reserve.

Currently, rhenium, tungsten, molybdenum, etc. are used by snail industry steel plants, mainly smelting high-temperature resistant alloys.

Under the leadership of Song Shijia, he inspected 17 mines in the Korqin area of ​​the Blue Age. Although they are all super-poor mines, they still have mining value for the Blue Age.

Since most of these rare resources mined are reserves, they will not have a significant impact on normal market prices. Unless they are stuck, the Blue Era will enable strategic reserve inventory.

For example, a large part of the rare metals used in the snail industry are purchased from abroad and domestic raw materials as reserves.

This approach is also a common method in developed countries. For example, Japan and Goryeo, which are poor in resources, pay more attention to strategic reserves.

On the other hand, they deliberately do not exploit domestic resources and intentionally consume the country's rare resources.

The convoy parked on a salt-alkali wasteland. Huang Xiuyuan could see the distribution map of mineral exploration in the Blue Age through his laptop.

This land is a zirconium ore. Although the reserves are not small, if all of them are refined, they can reach 1.3 million to 1.5 million tons, but the mineral grade here is pitifully low.
