Abstract

The chemical industry of Qaidam Salt Lake has developed into the most advantageous industry with the characteristics of Qinghai Province.Based on resource endowment and industrial development foundation,the chemical industry of Qaidam Salt Lake will continue to expand and strengthen potassium fertilizer industry,focus on building magnesium salt industry,steadily expanding sodium salt industry,focusing on cultivating lithium salt industry and gradually expanding boron chemical industry.With the development of salt lake resources in breadth and depth,the bottleneck of science and technology in the development of salt lake chemical circular economy industry in Qaidam area has become increasingly prominent.The salt lake chemical industry chain,product chain and technology chain are short,and the processing value-added rate and technology content of products are low,which affect the optimization and upgrading of industrial structure.Therefore,key technologies are needed to promote the sustainable development of salt lake industry.The salt lake chemical industry chain in qaidam area was analyzed.It pointed out the key technical problems that must be solved to develop the cycle economy of salt lake chemical industry in Qaidam area:First,the dissolution mining technology of the difficulty to mine low grade solid potassium ore; Second,solid-liquid conversion technology of solid potassium ore;Third,key technologies of replenishment and balance of salt lake brine;Fourth,extension technology for efficient utilization of magnesium resources;Fifth,separation and extraction technology of rubidium,cesium,bromine and Iodine in salt lake;Sixth,separation and extraction technology of salt lake boron resources;Seventh,high efficiency separation technology of magnesium and lithium in salt lake;Eighth,development and deep processing technology of lithium resources in salt lake and separation technology of lithium isotopes.
