| So far,separation on complication polymetallic sulphide ore is still a problem in the mineral processing field.Beneficiation workers at home and abroad have done a great deal of research for many years about metal sulfide minerals separation,achieved a number of new research results.But beneficiation process being maturity at present has been difficult to achieve an effective separation,for Complication polymetallic sulphide ore being embedded properties complication,having multi-metal and so on.Many beneficiation process added a large a lot of lime in the flotation process for obtaining copper,lead,zinc and so on.But ph value pulp on gold and silver are sensitive to changes in flotation,because high alkalinity pulp(PH value 10～12) is not good to mineral flotation on gold and silver,reducing recovery for gold and silver,causing a terrible waste.The study based on comprehensive utilization of associated gold and silver from complication polymetallic ore,under the condition with Low-pH Value,progressing comprehensive recovery to associated gold and silver at the same time to ensure grade and yield not to be influenced.Let gold and silver enrich to copper,lead and zinc,gold and silver's sum total of comprehensive recovery is 80.97%and 82.00%,copper,lead, zinc,gold and silver obtain maximum comprehensive utilization.
