Method for preparing low-calcium magnesium oxide by purifying high-calcium magnesite
The invention discloses a method for preparing low-calcium magnesium oxide by purifying high-calcium magnesite, and belongs to the technical field of metal ore upgrading processing. According to the invention, a method of first calcining and then mixing is adopted, raw material waste is avoided, hydrochloric acid is taken as a chlorinating agent, experiment cost is greatly reduced, utilization of low-grade magnesite is increased, resource waste is reduced, high-quality low-calcium magnesium oxide (WCaO is less than 1.00%) is finally obtained, and the process flow is simple and easy to operate.
一种高钙菱镁矿提纯制备低钙氧化镁的方法，属于金属矿提质加工技术领域。本发明采用先煅烧后混合的方法，避免了原料浪费，同时以盐酸为氯化剂，大幅度降低了实验成本，加大了低品位菱镁矿的利用，减少了资源的浪费，最终得到了较高品质的低钙氧化镁(WCaO＜1.00％)，且工艺流程简单易操作。
