Abstract: This article is based on multi-elements, analysis copper phase and lead phase. The ore is main made of chalcoprite with the oxidation rate 25.8% and galena with the oxidation rate 28.88%. Adopt the process as follow, mix-flotation of copper and lead, separation of the concentrate of lead and copper, zinc flotation from tail. Use sodium sulfite+dichromate as the adjusting agent to contain lead, the bulk lead-copper concentration were separated.
