  • Thiosulphate as an alternative to cyanide for gold

    Jul 18, 20130183;32;AbstractThiosulphate is an attractive alternative reagent to cyanide for processing gold ores. It is relatively cheap and non toxic, forms relatively strong gold and silver complexes, and readily leaches gold ores in ammoniacal solutions, catalysed by Cu(II). It is particularly suited to carbonaceous ores where the recovery of gold by cyanide is poor.
