Abstract: Focus on the peculiarities of refractory gold ore containing rich arsenic and rich sulphur in Jiangxi gold mines, the paper propose a new method and technology of acidic aqueous chlorination of gold. The research results indicate that this technology has some advantages of low cost, high immersion speed, high leaching ratio and low environmental pollution, this technology is a new way of hydrometallurgical treating refractory gold ores of Jiangxi.
