Advances in Gold and Silver Processing

gold extraction but its' toxicity is a major concern for the environmentalist There are many alternative non-cyanide lixiviants, such as thiourea, thiosulphate, chlorine an'd hypochlorite etc., which may reduce environmental sensitivity. This paper will discuss the leaching characteristics of gold in hypochlorite leaching solutions. The dissolution of gold in a hypochlorite solution not only ...

initial hypochlorite species in solution produces reasonable gold recoveries. The amount of added HCl and hence the initial pH was found to have a major effect on gold leaching kinetics and maximum gold recovery. A high level of 9 g/L of added HCl causes HClO to be very reactive, producing very fast kinetics, reaching 67% gold extraction in 4 h ...

CHLORIDE HYPOCHLORITE OXIDATION AND LEACHING OF REFRACTORY ...

For extraction of gold from the refractory ores in which gold is surrounded by sul-fide minerals, oxidative pretreatment of the ore is essential to oxidize the sulfides and expose gold. Pyrometallurgical oxidation by roasting is encountered with environmen-tal limitations; thus hydrometallurgical methods are preferred. These methods include pressure oxidation (Long and Dixon, 2004), bio ...

Previous studies have shown that in the process of gold extraction with a hypochlorite solution in close to neutral medium, the gold is reprecipitated from solution to the ore. Thus, gold is extracted from the ore, but does not remain in solution. To studying the process of gold reprecipitation in pregnant solutions depending on the pH of the medium a model material was used. A fixed amount of ...
