摘要：
The poor selectivity of cyanide has accelerated investigation of alternative agents. High reagent consumption and uncertain gold and silver recovery has opposed large-scale application. A flowsheet demonstrates that these problems can be overcome by adding SO//2 to the leach pulp and washing the residue with a thiourea solution. Further development is directed towards carbon in pulp technology.
