四川某锂多金属矿综合回收试验研究

Experimental Research on Comprehensive Utilization of a Multimetallic Ore Containing Lithium in Sichuan Province

对四川某锂多金属矿进行了选矿试验研究。针对该矿石的性质,采用"重—磁—浮"联合流程,获得了品位(TaNb)2O549.55%、Ta2O5回收率59.02%、Nb2O5回收率65.54%的钽铌精矿和品位52.16%、回收率80.04%的锡精矿以及品位5.53%、回收率72.68%的锂精矿。试验结果表明,该工艺合理可行,选矿指标较为理想,实现了资源的综合回收利用。

The experimental research on comprehensive utilization of a multimetallic ore containing lithium in Sichuan province was carried out. Directed at characteristics of ore, a combined flowsheet of ＂gravity - magnetic - flo tation separation＂ was adopted. A Ta- Nb concentrate of 49.55% （TaNb）2O5 was obtained with the recoveries of Ta2O5 and Nb2O5 is 59.02% and 65.54% respectively,and a tin concentrate of 52.16% Sn was obtained with a recovery of 80.04% ,as well as a lithium concentrate of 5.53% Li was obtained with a recover）, of 72.68% from the run-of-mine ore containing 0.90% Li2O,0. 005% Ta2O5,0. 009% Nb2O5,0. 064% Sn. The test results showed that this technological flowsheet is rational and feasible, the metallurgical performances are satisfactory, and the objective of comprehensive utilization of mineral resources is realized.
