China is a large agricultural country, raising 20 percent of the world's population with 9 percent of arable land. Therefore, it's important to improve unit yield. According to statistics, fertilizer contributes 50 percent to increases in grain yield. China is the second biggest potash consumer in the world, and about 23.3 million hectares of its arable land lacks potassium, forcing it to import more than 6 million tons of potassium every year. The world's potash resources and potash market are monopolized by a few foreign companies, so the domestic potash supply has been held over a barrel for a long time, directly endangering China's food security.
ChemChina's Changsha and Lehigh institutes joined hands with SDIC Xinjiang Luobupo Potash Co to carry out research on potassium sulphate production using brine from Lop Nor's magnesium sulfate-containing salt lake. They successfully came up with a new process and technology to produce potassium sulphate. They developed technologies for brine exploitation, salt pan mineral collection, and key transportation and processing equipment. Special research was also carried out to recover kainite and develop transportation technology and equipment to solve problems in the massive mining and processing of the potash resources at Lop Nor. The biggest potassium sulphate production unit has been built in the west of the Lop Nor hinterland, marking a great achievement in China's potassium sulphate technology development. The technology can save 1.9 tons of fresh water per ton of product, or 2.3 million tons of fresh water a year, playing a significant role in the water-strapped area, according to Huang Junwei, director of the Lehigh Institute.
