Jul 13, 2016 VAT Leaching in Tanzania. At the Golden Cycle, Dorr and Akins classifiers make a sand-slime separation as shown in Table 11. The sands are conveyed to 10 leaching vats 50 feet by 15 ft. deep with a capacity of 1200 tons each. The initial leaching period is 48 hr. with solution containing 0.5 lb. cyanide per ton.
The video is desorption electrolysis system of Xinhai Tanzania gold project. Desorption electrolysis system is one of the key decive in CIP. In gold electrowinning process, when the electrolysis equipment is added with anions which are more easily absorbed by activated carbons, AuCN2 is replaced by anion and the gold desorption is achieved.
