60 years of potash development in China, the self-sufficiency rate is close to 60%

Xinhua News Agency, Xining, August 22 (Reporter Luo Xiaofei, Deng Wanli) After 60 years of development and construction, China’s potash industry has been expanding, from relying entirely on imports to the current self-sufficiency rate of nearly 60%, greatly enhancing the right to speak in the international potash market and promoting China’s food production.

This is what the reporter learned from the 2018 Potash Potash Conference and the Golmud Salt Lake Forum on the 21st. Potassium is one of the three major nutrient fertilizers for crops, and plays a pivotal role in ensuring agricultural production and food security. China is a country with potassium deficiency, and its resource reserves only account for about 2% of the world.

It is understood that China’s proven resource reserves are mainly in the Salt Lake Potash Mine, mainly distributed in the Qaidam Basin of Qinghai and the Lop Nur area of Xinjiang. With the completion of the two major potash bases, especially in the past ten years, China has broken through the low-grade solid potassium salt, tailings utilization, deep brine mining and other technologies, so that the potassium salt can be multiplied.

It is located in Chaerhan Salt Lake, Golmud City, Haixi Mongolian Tibetan Autonomous Prefecture, Qinghai Province, with a total area of 5,856 square kilometers. It is the largest soluble potassium and magnesium deposit in China. In 1958, the first batch of Salt Lakers went deep into the Gobi desert, overcoming the harsh natural conditions, and relied on people to pull the shoulder to produce 950 tons of potash, officially opening the prelude to China’s potash industry production.

In the past 60 years, China’s potash industry has grown from scratch, from small to large, from weak to strong, forming a complete set of industrial systems such as scientific research, design, equipment manufacturing, construction and installation, production, sales, and agrochemical services. The strength has been continuously enhanced, and its potash production technology and single-set production capacity have reached the international leading level.
