Recovery of gold from thiourea solutions by flotation

A laboratory investigation was undertaken on the gold-thiourea system over the whole pH range, aiming at the separation of gold by flotation from dilute solutions. Various surfactants were applied, of cationic, anionic and non-ionic type. Among the parameters studied were the initial concentrations of added surfactant and thiourea; emphasis was placed on pH 1.5 (typical in hydrometallurgical operations) and 11. The further addition of ethyl alcohol, acting mainly as a frother, was found to improve gold recoveries remarkably: the recovery reached over 95%
