常规提金工艺对含铜氧化型金矿石氰化处理不仅容易造成资源浪费,更会造成严重环境污染。为解决这些问题,通过研究采取在常规堆浸基础上,浸出液用电集法回收金银的工艺流程,克服了常规提金工艺处理该类型金矿石经济效益差和对环境污染大等问题,取得了较高的金、银、铜综合回收比例。本文不仅详细阐述了该工艺工作流程、原理和注意事项,而且将该提金工艺实验推广应用于其他氧化型金矿石的金银提取。
Conventional gold extraction process cyanide oxidation of copper-containing gold ore not only easily lead to waste of resources, but also cause serious environmental pollution. In order to solve these problems, the paper studied the technological process of recovering gold and silver by leaching liquid on the basis of conventional heap leaching and overcoming the problems of poor economic benefit and large environmental pollution caused by the conventional gold leaching process, A higher proportion of gold, silver and copper recovery. This paper not only elaborates the process flow, principles and precautions, but also extends the gold extraction experiment to the gold and silver extraction of other oxidized gold ores.
