  Comparison of methods of gold and silver extraction from

  Thiourea leaching of the basic iron sulphate/lead sulphate product extracted 83–92 of the gold and 39–96 of the silver with thiourea consumptions of 33–132 kg/t. Assessment of the results of this research indicate that direct cyanidation may be a marginally economic method for currently produced products.
