Analysis of Occurrence State of Lithium and Aluminum in a Clay-Type Lithium Mine in Anning,Yunnan Province and Experimental Study on Comprehensive Recovery
摘要
Abstract
The main components of a clay-type lithium mine in Anning,Yunnan Province are diaspore,kaolinite,lithium chlorite,and boehmite.The chlorite-kaolinite aggregate is closely related to the embedding of diaspore and boehmite,and the inclusion with each other will be more serious in the sorting process.The highest theoretical grade of Li2O in the lithium concentrate is 0.84%.It belongs to low-grade refractory high-bauxite clay-type lithium ore.In order to develop this resource,on the basis of the study of ore properties,the beneficiation experiment is carried out.BK410 is used as bauxite collector,and through the process flow of"one roughing-two sweeping-two concentration",the bauxite concentrate Al2O3 grade is 68.62%,the Al2O3 recovery rate is 38.50%,the SiO2 grade is 8.31%and the aluminum-silicon ratio is 8.26 by closed-circuit test;The flotation index of the lithium concentrate with a Li2O grade of 0.46%and a Li2O recovery of 91.20%.The research results can provide some basic technical basis for the development and utilization of this kind of clay-type lithium ore.关键词
