摘　　要：某硫化铜矿石中铜矿物种类多,矿石中有用矿物浮游性能差异较大。自投产以来,该矿一直采用常规浮选工艺,致使矿石中的有价金属铜及伴生贵金属金、银的浮选指标不佳;在此基础上,从矿石性质角度出发,本研究采用的部分快速浮选新工艺充分利用了该铜矿石中有用矿物的解离特性和部分铜矿物浮游速率差异,优化了选矿工艺流程,形成了适宜该矿石的精细选矿新工艺,同时采用高效选择性捕收剂Z-200,实现了对部分单体解离程度较好、浮游速率快的铜矿物的快收早收,减少了不必要的循环,显著提高了铜、金、银的浮选指标。There are many types of copper minerals in some sulfide copper ore, among which useful mineralS, floatability are quite different in the ore. since it was put into production, the mine has been using conventional flotation process, resulting in poor flotation indexes of copper, gold, silver. On this basis, from the nature of the ore, part of the fast flotation of new technology takes full advantage of useful minerals’ dissociation characteristics and differences, optimizes the process, and forms a fine beneficiation new technology appropriate to the ore. At the same time, high selectivity collector Z-200 was adopted, realizing rapid and early collection of the copper ore with good degree of monomer dissociation and fast floating rate, reducing unnecessary circulation and significantly improving the flotation indexes of copper, gold and silver.
