摘要
高硫原生含铜金矿石,是一种含硫化铁较高的铜金石英脉矿石。由于金主要赋存在硫化铁和硫化铜中,金与硫、铜的关系密切。金在矿石中呈不均匀嵌布,包裹金与粒间金占优势。鉴于上述情况,在选矿工艺中除产出一个含铜金精矿外,还需从Au—Cu—FeS_2混合金矿中分离出一个硫精矿。如何降低硫精矿中金含量就成为一个突出的问题。本文通过对一段磨选、氰化浸出、混汞浮选、阶段浮选等处理方案进行的探讨、寻求了合理的选别方案,取得了较好的指标。
The ore to be discussed here is a primary copper-gold ore containing a large amount of pyrite occurred in the quartz Lode. The gold in the ore is on intimate terms with sulphur and copper because it exsits mainlyin ferric sulphide and copper sulphide. Golds distribute in the ore unevenly and most of them are within or/and between the grains of Pyrite,Based on the facts metioned above, it is necessary to separate a pyrite concentrate, besides a copper-gold concentrate, from the Au-Cu-FeS2 ore in mineral processing, find how to reduce the gold content in pyrite concentrate becomes a main problem.In this paper, some treatment options such as one-stage grinding and concentration,cyanidation,amalgamation-flotation, and flotation in stages, etc were studied, a reasonable treatment option selected and good results obtained.
