黄金冶炼尾渣综合利用研究进展

Abstract

Abstract: Gold smelting enterprises in China annually will produce a large amount of tailings，which usually contain Au over 0.5 g/t，as well as some copper，lead，zinc，and other valuable elements.Due to technical or economic reasons，most companies can only stockpile the tailings for treatment.Not only a waste of resources，but also damage to the environment.So comprehensive utilization rate of gold smelting tailings is low in China.Through the analysis of utilization status of gold smelting tailings，the existing comprehensive utilization methods were studied and analyzed，to provide an important reference for the tailings′utilization，so as to make waste profitable and to realize clean utilization.

Key words: gold, tailings, comprehensive utilization, advance
