RESEARCH ON INTENSIFIED LEACHING OF A GOLD ORE IN GANSU PROVINCE

Xiong Tong

Abstract

Aiming at the problems of high leaching gold grade and low rate of gold leaching of a skarn-type gold ore in Gansu,this paper provides an access to the study of gold leaching rate of 91.08%~92.16%,with the approach of comparing the experimental data of 3.70 g/t of the gold by pre-oxidation,leaching while grinding,leaching aid and by oxygen extraction.The experimental research provides a significant reference for the research of cyanide leaching of gold.
