Title: Recovery Efficiency Study on a Gold Ore by Combined Process with Flotation and Leaching
Abstract: A representative gold ore sample subjected in this work was taken from Guangnan gold mine, Wenshan municipality, Yunnan province, China. The ore sample assays 2.21 g/t Au, and the gold element exists in oxides, sulfides and silicates. Detailed tests as flotation and leaching were conducted in order to make good use of the valuable element. A flotation concentrate which assays 19.48 g/t Au is obtained through a flotation process of one rougher, two scavengers and two cleaners under the grinding fineness of 90% -0.074mm. The flotation concentrate with rich Au content is a high quality feed for metallurgy. And the flotation tailings were subjected to leaching. After 24 hours, the leaching rate reaches 90%.
