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
