摘要：

针对金铜精矿采用中性催化加压预处理工艺，经试验，在温度180 ℃、氧分压1.8 MPa、催化剂0.14 mol/L的基本条件下，Cu浸出率为99.4%，浸液中残留∑Fe质量浓度仅为3.52 g/L，对后续回收Cu的精炼工艺非常有利。氧化渣以氯化浸金工艺浸出Au、Ag，浸出率分别为98.2%、90.3%，有价元素回收率高，工艺简单，环境效益好。

关键词: 金铜精矿, 中性催化加压浸出, 预处理

Abstract:

The pretreatment method based on catalytic pressure in neutral conditions was used for leaching gold and copper concentrates. The results suggested that 99.4% of Cu could be leached out from gold and copper concentrates when temperature was 180℃, partial pressure of oxygen was 1.8 MPa and amount of catalyst was 0.14 mol/L. The total of Fe was only 3.52 g/L in leachate, which was beneficial to recovery of Cu in the follow-up process. In the residue, 98.2% of Au and 90.3% of Ag could be leached out by chloride leaching gold process. The pretreatment process was straightforward and the environmental benefits.

Key words: gold and copper concentrates, neutral catalytic pressure leaching, pretreatment process
