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 CuII. It is particularly suited to carbonaceous ores where the recovery of gold by cyanide is poor.read more
