摘要：
Agitation leach experiments were conducted on 85-pct-minus-35-mesh gravity concentrates containing 21. 8 oz gold and 6. 4 oz silver per ton. 96. 9 pct gold and 90. 7 pct silver extraction could be achieved in 96 hours of agitation. Gold and silver were recovered from the pregnant solution by exposure to granular activated carbon in a countercurrent system. Carbon loadings of 2556 oz of gold and 502 oz of silver per ton were achieved.
