摘要/Abstract

摘要： 利用矿物自动分析系统(MLA)和X射线荧光光谱仪、原子吸收分光光度计等对广东某斑岩型锡矿小于2 mm的原矿进行工艺矿物学研究，考察矿物组成、嵌布粒度、连生及包裹关系。结果表明，锡石主要呈细粒浸染状嵌布于脉石矿物中，嵌布粒度细微，最大粒度约为0.250 mm，最小为0.001 mm，主要集中在0.020?0.090 mm之间，单体解离度仅为9.98%，连生体主要与石英、黄玉连生。约93%的锡石(硬度6.5)被石英(硬度7)、黄玉(硬度8)包裹或与之连生，属难磨难选矿石，原矿伴有少量钼、铋、钨、铜等有价元素。选矿原则流程可确定为优先浮选回收硫化矿(钼、铋、铜、钨)，窄级颗粒分别(或依次)重选回收锡石。
