摘要
对广东某地矽卡岩型多金属矿进行了工艺矿物学研究,查明了矿石中有用元素赋存状态、矿物组成和嵌布粒度等特性,探讨了该区矿石中钨的利用价值及利用途径。建议采用分段磨矿、分段选别的工艺流程,在较粗的磨矿条件下首先生产铁精矿和钨精矿,然后对尾矿细磨以便回收锡石和辉钼矿。
Process mineralogy characteristics of a skarn polymetallic ore from Guangdong were studied and the occurrence of valuable elements,composition and dissemination size of minerals were ascertained,meanwhile the utilization value and beneficiation approach of tungsten in the ore were investigated.A flowsheet of stage grinding and stage separation was recommended,with which iron concentrate and tungsten concentrate can be recovered after primary grinding,cassiterite and molybdenite can be reclaimed from fine grinded roughing tailings.
