After visiting the Northern Nuclear Fuel Co., Ltd., Yang Jie also inspected the construction of the tailings dam and the nearby industrial park.

The tailings dam is now surrounded by a towering windshield that cuts off the sewage that seeps out of the dam's body, which is then pumped to a sewage plant for treatment.

The water from the tailings dam has been drained and is being pumped to the sewage treatment plant.

Although it has not yet snowed in Baotu City, strong winds have blown through the dense round holes in the windshield wall, and the scene of the original windy tailings dam flying sand is not visible.

Longyuan Rare Earth Technology Co., Ltd. built a tailings sand conveyor belt on top of the tailings dam to send a large amount of tailings sand to an industrial park a few miles away for sorting, enrichment and smelting.

Huaxing Technology Group Co., Ltd. quickly moved after determining the treatment technology plan of the tailings dam, and the appearance around the tailings dam has changed dramatically in more than two years.

Now Huaxing Science and Technology Group Co., Ltd. is investing in the construction of a comprehensive industrial park here, Longyuan Rare Earth Technology Company, Huaxing Chemical Group, Zhongyuan Metallurgical Technology Co., Ltd. and other companies are all gathered in the industrial park.

Yang Jie regards Baotu City as a strategic raw material base of Huaxing Technology Group Company, and is naturally willing to invest money here, and Baotu City and the Provincial Party Committee attach great importance to this, and the construction speed is extremely fast.

Huaxing Chemical Group Co., Ltd. has also invested in the construction of the largest fluorine chemical production base in the northern region, with five fluorite flotation production lines, two fluorite dry grinding production lines, with an annual output of 120,000 tons of acid-grade fluorite powder and 30,000 tons of ceramic-grade fluorite powder production capacity, in addition to investing in the construction of an anhydrous hydrofluoric acid production line, with an annual production capacity of 50,000 tons, which is the largest high-purity anhydrous hydrogen fluoride in China, and also built a hydrohydrofluoric acid production line.

Anhydrous hydrofluoric acid and hydrohydrofluoric acid are both colorless liquids, volatile, with strong pungent odor and strong corrosiveness, it is a key raw material for the production of various organic and inorganic fluorides and fluorine elements.

In particular, anhydrous hydrogen fluoride is an important raw material for fluorine chemical industry, and these raw materials are also in short supply after being put into production.

When Yang Jie inspected the factory of Huaxing Chemical Group Company, he was also in a good mood after seeing the busy situation of the factory.

The proton exchange membrane used in the fuel cell of Huaxing Technology Group Company needs to use hydrofluoric acid, and Huaxing Technology Group Company needs to use a large amount of hydrofluoric acid in the supply of a variety of ion membranes.

In addition, Huaxing Photovoltaic Technology and Huaneng Nuclear Power Technology Group Co., Ltd. both need to use lava, which requires hydrofluoric acid raw materials to prepare.

Huaxing Technology Group Co., Ltd. itself has a very large demand for fluorine chemical raw materials, and Yang Jie also chose Baotu City, a place with huge fluorite minerals, as a fluorine chemical base.

After Huaxing Chemical Group Co., Ltd. invested and built a factory here, it also quickly brought billions of output value to Baotu City.

This is only the business of Huaxing Chemical Group Company, Zhongyuan Metallurgical Technology Co., Ltd. invested in the construction of scandium alloy and niobium alloy production line with an annual output of 10,000 tons, which is already the largest factory in China, with an output value of tens of billions.

In addition, Longyuan Rare Earth Technology Co., Ltd. has established a 20-ton high-purity scandium oxide production line, and has also established a high-purity niobium oxide production line, and now the output value of the two lines is also tens of billions, and the two production lines have been put into operation for less than a year.

Huaxing Technology Group itself naturally uses a large number of these high-end materials first, and supplies them to other domestic enterprises if there is a surplus capacity.

Now it has become the world's largest production base of high-purity scandium oxide and niobium oxide, providing a variety of grades of scandium alloy and niobium alloy materials through a stable supply of large quantities and low costs, providing support for the wide application of these two high-end materials.

In addition, Longyuan Rare Earth Technology Co., Ltd. has also established a production line of nuclear pure thorium, and now this production line can also provide 10 tons of nuclear pure thorium products.

Although the current domestic thorium-based molten salt reactor nuclear power plants do not use so much pure nuclear thorium, most of the thorium produced by this production line will be stored in containers.

It took less than 200 million yuan to build this production line, and the cost of preparing nuclear pure thorium is actually very low.

A gigawatt reactor of conventional heavy water reactor and pressurized water reactor consumes 30 tons of low-enriched uranium nuclear fuel every year, and the cost of nuclear fuel assemblies alone is more than 30 million, and thorium-based molten salt reactors use molten salt, which does not require the preparation of nuclear fuel assemblies, and the cost is lower.

In order to build a warehouse for storing nuclear pure thorium, the cost is much higher than the construction of a nuclear pure thorium production line, and Huaxing Technology Group Co., Ltd. is still paying for it.

In addition, the output of the rare earth production line built by Longyuan Rare Earth Technology Company here is also not small, but the rest to meet its own needs is basically stored by itself, and it is rarely sold to the market.

Huaxing Technology Group Co., Ltd. has invested tens of billions of yuan in Baotu City in a few years, but the comprehensive industrial park here has generated tens of billions of output value this year, and the scientific and technological content of the industry is very high, which has become a new strong engine for the economic growth of Baotu City.

In comparison, in addition to its own rare earth business profits, Baotou Iron and Steel Group has continued to lose money in the steelmaking business, although the revenue of the entire group company is tens of billions, but the profit margin is very low.

The output value of the comprehensive industrial park invested and built by Huaxing Science and Technology Group Company here has exceeded that of Baotou Iron and Steel Group Company, and Huaxing Science and Technology Group Company is not a central enterprise, and a lot of taxes are left in the local area, which makes the attitude of Baotu City and the Provincial Party Committee very different.

Yang Jie's inspection here did not inform the local government, but the news of his inspection in the comprehensive industrial park had already alarmed the officials in Baotu City, and the number one in Baotu City called.
