Chemical mines: accelerating the pace of green and intelligent

The rise and fall of chemical mining is related to the development of China's chemical industry and the entire national economy
.

With the centuries of the party’s history, the development and construction of chemical mines in China has also made rapid progress.

From 1980 to 1985, the cumulative investment in chemical mines in China was 2.
12 times the total investment in the previous 30 years, and the production capacity of phosphorous and sulfur standard ore formed was greatly improved
.

From 1986 to 1990, China's chemical geology and mining industry showed a good momentum of steady development, greatly exceeding production targets
.

The total output of phosphate rock reached more than 80 million tons, the total output of chemical pyrite reached more than 20 million tons, and the output of potash, boron ore, alunite and other chemical minerals also greatly exceeded the plan

In 1990, the output of China's phosphorus and sulfur mines jumped to the third and fourth places in the world respectively.
A 200,000-ton/year potassium chloride production plant was built, which filled the domestic gap and initially formed a relatively complete chemical geological mining industry system
.

Following the Huangmailing Fertilizer Project and Wengfu Phosphate Mine, in 1991, the Dayukou Fertilizer Project of the World Bank project officially started construction, Zhangcunping Phosphorus Mine, Haikou Phosphorus Mine, etc.

Entering the 21st century, China's chemical mining industry has developed rapidly, and the industrial concentration has been continuously improved.
The mining, processing and trade volume ranks first in the world, and its position in the world's mining structure has become more prominent
.

At present, China’s main chemical and mineral products basically meet the needs of chemical fertilizers, chemical industries and other industries for mineral raw materials.

　　The rapid development of the chemical mining industry has also benefited from the greatly improved mining efficiency of enterprises
.

In recent years, the R&D and application of digital and intelligent technology and equipment has enabled China's chemical mines to abandon the traditional manual mining mode, realize intelligent and green mining, greatly improve the mining efficiency of enterprises, and promote the high-quality development of the industry

　　The acceleration of the construction of China's ecological civilization has also brought major opportunities for the development of green mining
.

In May 2017, the Ministry of Land and Resources, the Ministry of Finance and other departments jointly issued the "Implementation Opinions on Accelerating the Construction of Green Mines" to comprehensively promote the construction of green mines

　　The breakthrough of key technologies in the industry has also laid a solid foundation for the improvement of quality and efficiency and green development of China's chemical mining industry
.

In 2018, Yunnan Province developed the largest column flotation beneficiation technology in China and successfully applied it.

　　By establishing a long-term cooperation mechanism with universities, chemical mining companies aim to build green and smart mines, and to achieve intelligent management and control of safe production as the technical research direction, they have carried out research on the combination of high-efficiency mining technology and management and control methods, as well as filling mining
.

At present, these technologies have been applied in some chemical mining companies, increasing the recovery rate from 50% to 90%, improving resource utilization and corporate benefits
