从选铜尾矿中回收钨的选矿工艺研究

Mineral processing research on recovering scheelite from a copper tailings

摘要:

针对某选铜尾矿中钨矿物主要以白钨矿为主、且细泥含量高的矿石性质，采用脱泥-浮选-加温精选工艺流程，并采用广州有色金属研究院研制的回收钨的高效捕收剂 T AB-3，对WO3品位0．23，的选铜尾矿，可获得WO3品位52．17，、回收率74．25，的白钨精矿，实现了从选铜尾矿中综合回收钨的目标．

Abstract:

According to the ore properties of copper tailings ,the main tungsten mineral is scheelite ,and the copper tailings contains high amount of fine slime . T hen the technological flow sheet of desliming-grinding-flotation-heating process and the recovering tungsten efficient collector TAB-3 developed by Guangzhou Institute of Non-ferrous Metals were adopted . When the WO3 grade of copper tailings is 0 .23， ,the scheelite concentrate containing WO3 52 .17， with the recovery of 74 .25， are obtained ,and the goal of recovering tungsten from copper tailings is realized .
