Experimental Research on Mineral Processing Technologies for a Gold Ore from Gansu Province

Zeng Xiao-bo

Abstract

According to the mineralogical characteristics of the gold ore,an experimental research on mineral processing technologies is conducted.The leaching rate of gold can reach 94.01% by conventional all-sliming cyanidation method;the gold ore that was crushed to-15mm and-25mm can get leaching rate of 87.18% and 84.28% by column leaching tests.The experimental results indicated that the in-situ heap leaching technology is available for processing this kind of gold ore.
