摘要:

黄金是稀贵金属,具有货币和商品双重属性的特殊资源性产品,黄金具有很大的需求市场。目前,国内外对含氰毒浸金法主要的预处理方法有焙烧氧化法、热压氧化法、生物氧化法、化学氧化法、堆浸法、微波氧化法等。而对于难处理金矿的无氰毒浸金法有硫脲法,卤化法,多硫化物法,硫代硫酸盐法,浮选法等。因此正在不断寻求新的环保型的新方法。

Abstract:

The gold is a sparse precious metal, having the special resources product of the currency and merchandise dual attribute, the gold has a very big need market. Curently prepare the processing method to have already baked to burn to oxidize a method, heat to press to oxidize a method, living creature to oxidize a method, chemistry to oxidize a met}lod, heap to immerse a method, microwave to oxidize a method mainly etc. towards containing the cyanotype poison to immerse the gold method at home and abroad. But for dificult processing gold mine of immerse without the cyanotype poison the gold method contain the thiourea method, the halide turns a method, many sulphide metthods, the sulphur generation vitriol method, float to choose a method etc. Therefore just in the new method that looks for the new environmental protection type continuously.

Key words: Gold, Dificult processing gold mine stone, Pre-processing method, Prospect
