THIOSULPHATE LEACHING – AN ALTERNATIVE TO CYANIDATION .

Like cyanide, thiosulphate leaching is an alkaline process (usually operated in the pH 8 to 10 range) so there are no concerns with corrosion and materials used in construction, and the process can be applied to heaps and dumps, or to stirred tanks. The thiosulphate process offers advantages over cyanide leaching in the following situations:
