中文摘要:
      铜矿中伴生的金银矿物是重要的贵金属资源,其高效利用一直是研究的热点及难点。针对国内铜矿伴生金银资源特点,从工艺矿物学、选矿工艺、浮选药剂3个方面进行了系统评述,指出了现阶段伴生金银综合回收技术存在的问题。提出详细研究伴生金银的工艺矿物学特性,选择合理的磨矿细度和选矿工艺流程,根据伴生金银可浮性,研发新型、组合药剂,加强铜硫分离,提高载体矿物铜精矿的回收率,是铜矿伴生金银回收利用的重点研究方向。
英文摘要:
      The associated gold and silver minerals in copper mines are important precious metal resources. Their efficient utilization has always been a hot and difficult point of research. According to the characteristics of domestic associated gold and silver in copper mines the recoveries of gold and sliver were systematically reviewed from three aspects, process mineralogy, mineral processing technology and flotation reagents. The current problems for the comprehensive recovery of associated gold and silver were pointed out. It is proposed to study the process mineralogy characteristics of associated gold and silver in details, select reasonable grinding fineness and beneficiation process, develop new and combined reagents according to the floatability of associated gold and silver, strengthen the separation of copper and sulphur, and improve the recovery of the carrier copper concentrate as the key research directions for improving the recovery of gold and silver associated with copper mines.
