摘要/Abstract

摘要：

以氰化法提金的原理为基础,综合分析矿石中金的堆浸,收集有关采金实践经验,论述了氰化法提金中金溶解的原理,杂质对金溶解的影响,氰化物溶液的稳定性以及氰化物污水的处理等问题。以99. 9%的金作为原料,经王水溶解,用乙醚做萃取剂、草酸做还原剂,可获得99. 999%的纯金。经提纯的金进行杂质检验,完全达到了高纯试剂要求的技术指标。目的是配合当前单位、个体采金的需要,以提高其工作效率及经济效益。

Abstract:

Based on the principle of cyanidation extract gold,we comprehensive analysis of gold piled in the ore, and collection the practical experience of extracting gold. We discuss the principle of gold dissolving in cyanidation extract gold, the impact of imputities on gold dissolving, as well as the stability of cyanide solution and the treatment of cyanide waste water, and so on some of questions. We can use 99. 9 percent of the gold as raw materials, and it is dissolved by aqua regia, use ether as extraction, oxalic acid as reducing agent,we can gain 99. 999 percent of pure gold.We test the impurities for purity gold, and technical indicators reach to the requirements of high2purity reagents. The purpose of thismethod is cooperate with the needs of extracted gold, in order to improve effectiveness and cost-effective.

Key words: Gold, Cyanidation, Cyanide solution, Solubility, Complex compound, Purification
