高硫难选白钨矿选矿回收技术研究
Research on Beneficiation of a Refractory High-sulfur Scheelite with high sulfur content
摘要
Abstract
Based on the process mineralogy,the process of pre-desulfurization-flotation of scheelite at ambient temperature was proposed for the low-grade scheelite ore in the eastern Inner Mongolia.The closed-circuit test showed when the grinding fineness is 64.5％ and butyl xanthate,butylamine aerofloat,kerosene are combined to use the desulfurization rate can reach 86.02％The test can obtain a concentrate with the WO3 grade of 55.31％,a recovery of 63.92％ and the grade S of 0.23％ by adopting a closed-circuit test of one roughing five cleaning and two scavenging at room temperature from a product after desulfurization.关键词
