Nowadays, there are many gold leaching processes, and the dominant one is cyanidation, but virulence of cyanidation seriously endangers environment human health. In order to reduce environmental pollution improve recovery rate gold, metallurgical workers put forward a variety new methods, which can be roughly divided into two types: develop pretreatment technology on basis traditional method; T...

This paper presents a feasibility study of a wearable helmet in order to protect mine workers specially of goldmines from carbon monoxide poisoning and cyanidation. Carbon monoxide(CO) poisoning is a common problem faced by the workers of coal, gold and many other mines. On the other hand cyanidation problem occurs in gold mines only during ore processing. Current safety systems for mine worker...
