Potash is a usable mineral resource resulting from accumulation of soluble potassium-bearing saline minerals in nature. It includes potassium-bearing brines and soluble solid potassium salts (e.g. sylvite, carnallite etc.) formed by evaporation, concentration and deposition of potassium-bearing water bodies.
In the world 95% of the potash is used for fertilizer. The main products are potassium chloride and potassium sulfate. It is one of the three major indispensable fertilizers. Only about 5% is used in industry. In industrial uses, 35% is used in the manufacture of detergents, 25% in the glass and pottery industry, 20% in the textile and dyeing industry, 13% in the manufacture of drugs, and the rest in the canned food, tanning, electric appliance and metallurgical industries. Potassium chlorate, superphosphate and nitrate are important ingredients in matches, fireworks, explosives and rockets.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,cement production line,vibrating screen Welcome all of you to visit our official website:http://www.hxjqchina.com/company.htmlshaking concentrator:http://www.crusher-machine.com/33.html
Before the 1950s there was no potash industry in China and the soil fertility was maintained by farm manure. In the late 1950s China found the liquid potassium-magnesium salt mining area in the Qarhan Playa, Qinghai, and in 1963 China again found the Mengyejing solid potash mining area. Through a few decades of work, now an integrated mineral and fertilizer complex of liquid potassium-magnesium salt has been established in the Qarhan Playa and a potash production base has been formed there.
The soluble potash reserves demonstrated in China are not large and cannot meet the present enormous demands of agriculture for fertilizer. Therefore, potash is one of China’s urgently needed mineral resources.
