摘要/Abstract

摘要：

含铜金矿普遍存在氰耗高、尾渣金品位高的问题,影响矿山的经济效益。我们通过试验研究,查明了含铜金精矿的纯氧氰化浸出的一般规律,提出了高氰化钠浓度、纯氧或富氧浸出等改进工艺的技术措施,使氰渣中金品位和单位氰耗降低,明显缩短了氰化时间

关键词: 含铜金矿, 氰化, 纯氧

Abstract:

Cyanide leaching of a copper-bearing gold sulfide concentrate using oxygen was investigated.Some factors affected on cyanidation of gold in the concentrate,such as the dissolved copper,the concentration of oxygen in pulp and the initial cyanide concentration,were discussed.A technical scheme for processing the Cu bearing concentrate and optimized operating conditions were proposed.

Key words: cyanidation, copper-bearing gold concentrate, oxygen
