System and method for obtaining high-purity light burning powder and high-grade magnesium salt by grading and purifying magnesite
The invention discloses a system and a method for obtaining high-purity light calcined powder and high-grade magnesium salt by grading and purifying magnesite, and relates to the technical field of magnesium salt chemical industry, high-silicon low-grade magnesite is subjected to winnowing separation, hydration hydrocyclone separation and carbonation separation to obtain the high-purity light calcined powder, active magnesium oxide and light magnesium carbonate or high-purity magnesium oxide. Compared with the prior art, a flotation agent is not adopted for mineral separation, environmental pollution caused by the existence of soluble salt in the flotation agent is avoided, the production cost for producing the high-purity light burning powder from the low-grade magnesite is greatly reduced, the economic benefit is remarkable, the large supply problem that enough high-purity light burning powder is obtained from the low-grade magnesite is strategically solved, and the method is suitable for industrial production. The method has great social significance.
一种菱镁矿分级提纯获得高纯轻烧粉和高档镁盐的系统和方法，涉及镁盐化工技术领域，高硅低品位菱镁石经风选分离、水化旋液分离、碳酸化分离获得高纯轻烧粉、活性氧化镁以及轻质碳酸镁或者高纯氧化镁。同现有技术相比，本发明不采用浮选剂选矿，不会因浮选剂中可溶性盐的存在造成环境污染，大幅降低了低档菱镁石生产高纯轻烧粉生产成本，经济效益显著，从战略上解决了以低档菱镁石获取足够数量高纯轻烧粉的供给大问题，具有重大社会意义。
