60 million tons of "magnesium damage" in Qaidam Salt Lake turned into "magnesium treasure"
Our news (reporter Xing Shengxiang) Reporter recently learned from Western Mining Group Co., Ltd. that 60 million tons of "magnesium damage" hydrochloromagnesite in Qaidam Basin has become "magnesium precious" through technological innovation, which has sold well outside China and filled the gap in China's magnesium hydroxide and magnesium oxide high-end products.
Qinghai is a large province of salt lake resources, large and small salt lakes scattered in the vast Qaidam basin, only proved reserves of magnesium resources accounted for more than 90% of China's total magnesium resources. For a long time, the resource development of Qaidam Salt Lake is mainly based on the production of potash fertilizer, and 12 tons of hydrochloromagnite are produced for every 1 ton of potash fertilizer. Due to the limitation of process technology, magnesium resources have not been developed and utilized efficiently, resulting in "magnesium damage" caused by the change of salt lake composition.
"Hydrochloromagnite has formed an artificial lake in Qarhan area, and the current reserves are more than 60 million tons, which has seriously restricted the production of potassium fertilizer in salt lake." Said Sheng Yuyong, chairman of Qinghai West Magnesium Industry Co., LTD.
In order to turn hydrochloromnesite into treasure, the West Magnesium Industry Company under the West Mining Group, relying on its own advantages, combined with Chinese experts and top technical teams, through repeated trials and continuous optimization, completely solved the key technical problems of chemical synthesis of high purity magnesium hydroxide. It invented a new process of "Salt Lake brine - ammonia-lime combined method for continuous production of high purity magnesium hydroxide", obtained the patent for continuous dissolution of Salt lake water magnesite for producing high concentration magnesium chloride solution, and filled the gap in China's magnesium hydroxide and magnesium oxide high-end products.
According to Sheng Yuyong, the company produced high purity magnesium hydroxide, 5 to 6 micron ultrafine powder, 1 to 2 micron ultrafine powder, high purity magnesium oxide, fused magnesia and other high-end products have been in the forefront of the world, has been exported to France, South Korea, Japan, Turkey and other countries, mainly used in flame retardant, medicine, plastics, rubber and high-end refractory materials, etc. The product is in short supply.
