  • Gold Silver Leaching Methods

    Leaching Process Leach Solutions. Although it is possible to leach gold and silver with several types of solutions all current operations use sodium cyanide (NaCN) mixed in water at strengths of about 1 lb/ton (0.5 g/kg) of solution or 0.05 pct. Strengths encountered in current operations range from 0.3 to 5.0 lb/ton (0.15 to 2.5 g/kg).
