Method for comprehensively utilizing amblygonite ore
The invention discloses a method for comprehensively utilizing amblygonite ore, which comprises the following steps of: recovering a phosphorus resource in amblygonite into phosphoric acid, recovering an aluminum resource into aluminum oxide slag, and carrying out leaching-purification impurity removal-carbonization lithium precipitation/phosphate lithium precipitation on the lithium resource to obtain lithium carbonate/lithium phosphate and sodium sulfate products. According to the invention, efficient separation of lithium and aluminum in amblygonite is realized, and resource utilization of aluminum and phosphorus is also realized. The method is simple in technological process, low in equipment requirement and high in practicability.
本发明公开了一种锂磷铝石矿综合利用的方法，该方法将锂磷铝石中的磷资源回收为磷酸，铝资源回收为氧化铝渣，锂资源经过浸出–净化除杂–碳化沉锂/磷酸盐沉锂得到碳酸锂/磷酸锂和硫酸钠产品。本发明实现了锂磷铝石中锂铝高效分离，同时还实现了铝磷的资源化利用。本发明工艺流程简单，设备要求低，实用性强。
