前言我国蕴藏着各种储量的金铜矿及伴生矿。对于中小型矿山的就地选冶处理及大型矿山的某些选矿产品的冶炼来说,采用传统的焙烧-浸铜-氰化提金工艺显然经济上是不适宜的。这样就需要研究其他冶炼工艺的可行性,以便推荐一种技术经济合理的流程,既便于中小企业在投资省、效益好、污染小的条件下实施,又有利于大型企业为提高选矿回收率对选矿产品结构作调整。本工艺所研究的矿石属多金属矿物,主要有回收价值的为铜、银和金。一般处理这类矿石的方法有三种:一是采用传统的焙烧-浸出-氰化。这个方法首先要保证有制酸
Preface China holds a variety of reserves of gold and copper and associated ore. The traditional roasting-leaching of copper-cyanide leaching is clearly not economically viable for on-site metallurgy at small and medium mines and smelting of some beneficiation products at large mines. In this way, the feasibility of other smelting processes needs to be studied in order to recommend a technically and economically reasonable process that is not only conducive to the implementation of small and medium-sized enterprises under the conditions of investment, good efficiency and low pollution, but also conducive to large enterprises in order to increase the rate of beneficiation recovery Dressing product structure to be adjusted. The ore studied by this process is a kind of polymetallic mineral, and mainly has the recovery value of copper, silver and gold. There are three general ways to deal with this type of ore: First, the traditional roasting - leaching - cyanidation. This method must first ensure that there is acid
