四川大陆槽稀土尾矿回收萤石实验
Recovery of Fluorite from a Low-grade Rare Earth Tailing in Sichuan
摘要
Abstract
This is an article in the field of mining processing engineering.This article takes Dechang Daluchao rare earth mineral processing tailings as the research object,conducts a beneficiation test study on fluorspar recovery,and determines the beneficiation process flow and reagent of"flotation desulphurization-mixed flotation-flotation separation of fluorite,strontium and barium"for fluorite recovery.In the flotation test,the new MQY collector and DC-2 high-efficiency inhibitor were used to efficiently capture fluorite while achieving precise separation of fluorite and gangue minerals.In the final full-process test,a fluorspar concentrate with a CaF2 grade of 94.39％and a recovery rate of 51.41％was obtained.The test indicators were relatively ideal.This article tested and verified the feasibility of recovering fluorspar from the Dalunchao rare earth tailings.The final beneficiation process is reasonable and has good test indicators.It can be used as a technical basis for the utilization and recovery of fluorspar resources in the Dalunchao rare earth tailings.关键词
