A Study on Treating Technology for A Refractory Gold Ore

Ping Wu

Abstract

A treating technology which was mainly composed of fixing sulfur and arsenic by roasting and cyanide leaching for gold was tested.Test results show that adopting the technology treated a refractory gold ore,technic indexes obtained are as follows∶fixing rate of sulfur is 95.55%,fixing rate of arsenic is 95.49%,and leaching rate of gold is 93.18%,It provides an effective way for exploitation and utilization of high sulfur gold ore containing arsenic.
