中文摘要:
      针对某细碧岩型铜矿进行了工艺矿物学和选别研究。该铜矿主要为硫化铜矿,少量氧化铜矿,含铜1.20%,其中硫化铜占80%,其他形式铜占20%。其矿物组分及结构构造不算复杂,铜矿物主要为黄铜矿、斑铜矿,脉石矿物有斜长石、绿帘石、绿泥石及石英等。通过采用一次粗选、一次精选和一次扫选的开路试验流程,可获得试验指标为铜精矿产率3.80%,铜品位23.40%,铜回收率75.40%;尾矿中铜含量很低,仅为0.055%,损失率为4.07%的较好指标,闭路试验指标会更好。研究结果可为类似硫化铜矿的开发利用提供一定参考。
英文摘要:
      This paper studied the mineralogy and selection of a spilite type copper ore. The copper ore is mainly sulfide copper, a small amount of oxide copper which contained 1.20% of copper, among them 80% copper sulfide and 20% other types copper. Its mineral composition and structure are not complicated that copper deposits are mainly chalcopyrite and bornite and gangue minerals are plagioclase, epidote, chlorite, quartz, etc. By adopting one roughing, one cleaning and one scavenging, copper concentrate with yield of 3.80%, grade of 23.40%, and recovery of 75.40%, copper tailings with grade of 0.055%, and the loss rate of 4.07% were obtained. The results can provide a reference for the development and utilization of similar copper sulfide.
