Cu-Pb-Zn Dressing Process

Cu-Pb-Zn Production Line

[Introduction]: Adopting mixed flotation-concentrate regrinding process can reduce the grinding cost, and be easy to manage. Application of new non-toxic flotation reagents is efficient and environmental protection.

[Application]: Mixed flotation-concentrate regrinding process is applied for Cu-Pb-Zn sulfide ore.

Process Description

  • Creative process, low operation cost

    Cu-Pb mixed concentrate regrinding process saves the grinding cost without finely grinding all raw ore, and it makes further monomer dissociation to create favorable conditions for the separation of copper and lead.

  • Strengthen Flotation Process, Increasing Copper Concentrate Grade

    In rough flotation, the reagent is carried out strictly to control the reagent amount, realizing early recovery as possible. Reduce multiple recycling and valueless loss. Make the best of foam secondary enrichment, and wash the concentrate foam to reduce the impurities in foams according to suitable water adding. 

  • Copper-Lead Mixed Flotation Separation

    In flotation stage, the copper-lead mixed concentrates should be priority separated. After regrinding, the lead concentrates and copper concentrates are separated by flotation and respectively dewatering.

  • Zinc Flotation Separation

    After copper-lead mixed flotation and mixing the slurry, zinc concentrates are separated by flotation from tailings. After dewatering, the zinc concentrate product is required.
