Copper-lead-zinc ore separation flotation agent

More than 90% of non-ferrous metal ores use flotation technology, especially for those ores with fine grains and complex intergrowth. The flotation process can achieve the ideal separation effect, recover low-grade ores separately, and then enrich a variety of high-grade concentrates.

1. Separation of lead-zinc ore: Differential flotation process, flotation of lead and pressing of zinc.

Collectors: low xanthate, high xanthate, plankton. Separation in alkaline media.

Inhibitors: CN-, NaCN, kCN, ZnSO4, Na2OS3, Na2S2O3.

Activator: copper sulfate, then collected with high-grade xanthate.

2. Copper and zinc separation: Differential flotation process, flotation of copper and depressing zinc. If the separation difficulty exceeds 2, the suppression of zinc should be strengthened.

Collectors: low xanthate, high xanthate, plankton. Separation in alkaline media.

Inhibitors: CN-, NaCN, kCN, ZnSO4, Na2OS3, Na2S2O3.

Activator: copper sulfate, then collected with xanthate.

3. Separation of copper and lead: remove the reagent first, and then carry out flotation. Levitates copper and suppresses lead, or flotation lead suppresses copper.

• Floating copper and suppressing lead: widely used in secondary copper mines, Cu2 + ions dissolve too much and are easily suppressed.

• Levitates lead and suppresses copper: Widely used in primary copper ores.

The three methods of copper-lead-zinc ore flotation are introduced above. The main beneficiation equipment used in several flotation methods are ball mill, flotation machine, stirring tank, etc. If you want to know more about copper-lead-zinc ore For beneficiation process or other ore beneficiation process, welcome to consult our professionals.
