To achieve high gold recoveries, the values of the process parameters of thioureation may be pH 1; temperature, 208C; thiourea concentration, 100 grkg; pulp density, 20% and leaching time, 6 h. When the leaching temperature has been fixed at 608C, after 2 h of leaching high Au recovery about 87%. was attained, but thiourea consumption increased to 26 grkg.

Thiourea for Extraction of Gold & Silver from Silver Ores

Thiourea for Extraction of Gold & Silver from Silver Ores

Leaching Chemistry of Gold Silver and Manganese. Thiourea is a reducing and complexing agent and can be used for the processing of gold and silver. The redox potential of gold(I) and silver(I) thiourea complexes in acidic thiourea solutions are 0.380 and 0.023 V (vs SHE), respectively (Kazakov et al., 1983; Lodeishchikov et al., 1975).
