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.
The recovery of lithium from its ores is typically achieved through flotation, which involves the separation of valuable minerals from gangue minerals based on their differences in surface chemistry. There are several flotation methods that can be used for the beneficiation of lithium ores, including forward flotation, reverse flotation, and combined flotation.
The beneficiation process of barite mainly includes crushing, screening, washing, and flotation. The crushing stage usually uses jaw crushers and impact crushers. After crushing, the barite ore is screened and classified according to particle size.
