| Abstract: | The technology of covering membrane-dropping-heap leaching gold by copper ammonia thiosulfate was established .The run of mine ore treated directly by heap leaching,The leach recovery of gold is more than 80%. Gold was recovered effectively by solid extractant with high activity and specific surface from the leaching solution containing gold, the recovery, of gold adsoorption is more than 99 % and the amount of loaded gold is 22g/kg. Thiosulfate was recycled, its consumption is 5.78g/kg. The process has been applied to oxidizes type gold ore from Sichuan and the extended test of laboratory has been obtained satifactory results. |
