Abstract: The paper studied the characteristics of mineralogy of ore and the occurrence condition of silver in order to improve the accompanying silver rocovery of rate in Huaniushan lead-zinc sulfide mine.The results showed,through adopted to adding the combined reagent,cutting down properly the lead grade of flotation in major concentration,regrinding the rougher concentrate,and such sorts separate technology,that the recovery of accompanying silver was improved apparenlty,and created a better separation index of lead-zinc major metals.
