The mid-grade magnesia project has passed the acceptance and achievement evaluation organized by relevant provincial departments recently, which marks a major breakthrough in the key technology of high-purity magnesia industrialization in salt lakes. The overall technical achievements of the project "Research on Industrialization Technology of High Purity Magnesium Sand Made by Ammonia Process of Salt Lake Magnesium Resources" are in the leading position in the world. It has such remarkable advantages as less investment in equipment, high utilization rate of resources, good product quality, low comprehensive cost, energy saving and environmental protection in production process, etc. It can produce high purity magnesia and other high purity oxygen for the development of Salt Lake magnesium resources. Magnesium chemical has laid an important foundation, fully in line with the requirements of the development of circular economy, and is of great significance to the comprehensive development and recycling of resources.
The exploitation of magnesium resources in salt lakes has always been an important part of the exploitation of salt lakes in Qaidam, and it is also a technical problem to be solved urgently in the construction of Qaidam circular economy pilot area. Due to technical reasons, the salt lake resource processing enterprises in Haixi are unable to effectively utilize more than 30 million tons of brucite every year, resulting in waste of resources. In order to realize the effective utilization of magnesium resources, in 2005, the relevant departments of Haixi Prefecture declared to the Ministry of Science and Technology the project "Research on Industrialization Technology of High Purity Magnesium Sand Made by Ammonia Method of Salt Lake Magnesium Resources" on the basis of the major scientific and technological research project "Development and Research on Production Technology of High Purity Magnesium Sand Made from Salt Lake Brucite" in Qinghai Province during the Tenth Five-Year Plan and obtained To set up the project. After more than two years of implementation, the project has successfully solved many key technical problems in the industrialization process of producing high purity magnesia from Salt Lake magnesium resources, especially in the filtration and washing performance of high purity magnesia intermediate magnesium hydroxide, which has made significant breakthroughs and innovations.
