Thiourea Gold Leaching

For the thiourea process to compete industrially with cyanidation, it is essential to develop efficient process(es) to recover the gold from solution Research on the leaching of gold by thiourea has been reported extensively in the literature, but research on the recovery of gold from leach solutions has not been well documented Some methods for recovering gold-thiourea complex reported in .Therefore, in CIL, the cyanidation process is carried out simultaneously with adsorption on activated carbon, which is in direct contact with pulp in the cyanide solution.
