Experimental Study on Roasting Pre-oxidation and Cyanidation Gold Extraction Process for Refractory Gold Concentrate from Xinjiang

Zhao Fu-cai

Abstract

This paper studies the process mineralogy and roasting pre-oxidation and cyanidation gold extraction process for refractory gold concentrate from Xinjiang.Result shows that the gold recovery is up to 91.42% after roasting pre-oxidation of the gold concentrate and is 50.60% higher than conventional cyanidation.The result is important to the utilization of this kind of gold ore.
