Abstract

Abstract

Qinghai salt lake is rich in resources. However, due to the initial development only focused on the extraction of potassium chloride, a large amount of bischofite was generated from the discharged by-product of waste brine under the sun. It not only caused the waste of magnesium resources, but also did serious damage to the ecological environment of the salt lake. Therefore, the comprehensive utilization of bischofite resource needs to be solved urgently. The technology status and existing problems of the preparation of magnesium, magnesium oxide and magnesium hydroxide from the salt lake bischofite were introduced in this paper. Meanwhile, the development trend of the utilization technology of the bischofite in the salt lake was analyzed and forecasted.
