Although cyanide is a very efficient product in the industry it is very toxic (Bhat et al. 2012) because of which the cyanide usage as a leaching agent is a major issue (Hilson and Monhemius 2006) and many studies are being made to substitute this toxic chemical. The use of thiosulfate (S 2 O 3 2-) instead of cyanide is an alternative.
