金宝山铂钯矿选矿工艺研究

摘要

According to the process mineralogy characteristics of platinum-palladium ores from Jinbaoshan of Midu County, Yunnan Province, technique flowsheets featuring stage grinding, stage separation, and joint processes of flotation and magnetic separation, and relevant processing parameters were studied and selected, and good separation index can be obtained. Yet, as the grades of platinum and palladium in the concentrates do not change synchronously along with those of copper and nickel, the processing parameter can not be determined according the variation of grades of copper and nickel.%针对云南弥渡金宝山铂、钯矿矿石的工艺矿物学特点,研究确定了阶段磨矿、阶段选别,浮选与磁选相结合的工艺流程及相关工艺参数,得到好的选矿指标.但鉴于精矿中铂、钯的品位并不与铜、镍的品位完全同步变化,不能完全依靠铜镍品位的变化来确定选矿工艺.
