Alternative lixiviants to cyanide for leaching gold ores

Because of the similar stabilities of gold and silver bisulﬁde complexes, bisulﬁde leaching may be suitable for leaching gold ores with significant silver content (Hunter et al., 1998). The YES process uses naturally occurring, sulfate-reducing bacteria for the recovery of gold and silver from ores. Get price

2018/7/11Heap leaching has become a popular method of extracting gold, writes Nicolaas C. Steenkamp and Leon Louw. Heap leaching is used to extract gold, copper, silver, uranium, and iodine. This method was first employed to extract copper at the Bluebird mine in the US in the early 1960s, and then by several gold mines in the western parts of the US a few years later. Get price

Bioleaching gold recovery

• Thiourea leaching • This method was developed as a potential substitute for cyanidation (of gold as well as silver). Thiourea's lower toxicity and greater rate of gold and silver dissolution compared to cyanide give it an advantage inreaching commercial application before other non-commercial lixiviants [2].
