金矿石的新型环保浸出剂研究现状与应用进展
|
摘要
近年来,随着氰化物在金矿石浸出过程中所造成的环保压力急剧加大,越来越多的黄金矿山开始寻找氰化物的替代品。随着选矿技术的不断进步,以代替NaCN为目标的浸金药剂亦在不断推陈出新。从作用机理、特点及应用等方面介绍了传统无氰药剂和新型环保浸出药剂在金矿石浸出工艺中的研究与应用进展。与氰化物浸出效果对比表明,无氰药剂和新型环保浸出剂在黄金提取生产中替代氰化物的趋势越来越明显,并概述了金矿石的新型环保浸出剂未来的发展趋势。
In recent years, with the rapid increase of environmental pressure caused by cyanide leaching in the leaching process of gold ore, more and more gold mines began to look for alternatives to cyanide. With the continuous improvement of mineral processing technology, the gold leaching agents to replace sodium cyanide are constantly being introduced. We will introduce research progress of traditional non-cyanide agents and new environment-friendly leaching agents in the leaching process of gold ore from interaction mechanism, characteristics and application. By comparing with the effect of cyanide leaching, it is shown that the tendency of replacing cyanide with non-cyanide agents and environment-friendly leaching agents in gold extraction production was more and more obvious. The future development trend of environmental leaching agent for gold ore was summarized.
