Cheng Jiang

Abstract

The nature of a refractory gold ore in Guizhou was introduced.The technology for recovering gold from the ores was proposed.The gold recovery increased from 25% in direct cyanidation to 90% in roasting-cyanidation process.The results indicated that the roasting-cyanidation is a efficient method for the refractory gold run-of-mine ore.
