某斑岩型金铜矿选矿试验研究

介绍了某斑岩金铜矿的矿石性质,针对有用矿物的分布特征制定了金铜混浮选流程,并进行了一段磨矿、粗精再磨、中矿再磨对比试验,粗精再磨闭路流程指标最优,混合精矿产率2.35%、含金40.41g/t、含铜24.08%、金回收率84.40%、铜回收率89.51%。并提出了多收粗粒金的工艺方案。

Ore Dressing Test of a Porphyry Auricupride

The final sample of blended run of mine ore of a porphyry auricupride contained gold 1.26g/t ore and copper 0.66%.Under coarse grinding fineness,the process of roughing,two-stage cleaning and regrinding of rough concentrate after two-stage scavenging was selected to deal with the ore sample.The process achieved a mixed concentrate with a yield of 2.35%,gold 40.41g/t ore,copper 24.08%,a gold recovery of 84.40% and a copper of recovery 89.51%.It was determined that the ore was a free-milling auricupride and u...
