Abstract: Based on the research of process mineralogy to some low grade copper,lead and zincores containing gold and silver ore in Inner Mongolia,combining the value system of gold and silver,the main value component in the ore，the flow  project of concentrating gold and silver to copper and lead concentrates is confirmed.According to the technical study of bulk flotation of copper-lead，copper-lead separation，flotation of zinc later,the closed circuit,ore grinding，mixed flotation of copper，lead of one roughing,two scavenging,one concentrate，another grinding，two bulk concentrate，separate of copper，lead of one roughing,one scavenging,one concentrate，zinc flotation of one roughing,two scavenging,four concentrate，middling return in sequence,is determined.The copper concentrate of gold recovery 85.92%，silver recovery 50.99%，and the lead concentrate of gold recovery 5.50%，silver recovery 17.49% are gained.The total recovery of gold is 91.42%，the total recovery of silver is 68.48% in copper concentrate and lead concentrate.

Key words: Gold-silver Ore, Copper concentrate, Lead concentrate
