Embodiment 1
[0022] The combined beneficiation method of copper-lead-zinc-tin polymetallic sulfide ore consists of primary grinding of raw ore, mixed flotation of copper, lead and sulfur, secondary grinding and selection, separation of copper, lead and sulfur, lead flotation, and zinc flotation; In the mixed flotation, the beneficiation agent ethylene butyl mixed with xanthate is used as the collector of copper and lead minerals, and zinc sulfate and sodium sulfite are used as the inhibitor of zinc minerals; in the separation of copper, lead and sulfur, sodium sulfite and sodium thiosulfate are used as the lead and sulfur Mineral inhibitor, Z-200 is used as a collector for copper mineral sweeping. Calculated on the basis of 1 ton of raw ore, the first-stage grinding -200 mesh accounts for 70%, and the second-stage grinding -400 mesh accounts for 65%. The dosage is 40g, the dosage of zinc sulfate is 700g, and the dosage of sodium sulfite is 400g; the dosage of sodium sulfite in copper-lead-...

Calculated on the basis of 1 ton of raw ore, the first-stage grinding -200 mesh accounts for 65%, and the second-stage grinding -400 mesh accounts for 65%. The dosage is 40g, the dosage of zinc sulfate is 500g, and the dosage of sodium sulfite is 300g; the dosage of sodium sulfite in copper-lead-...
Embodiment 3
[0028] The combined beneficiation method of copper-lead-zinc-tin polymetallic sulfide ore is composed of primary grinding of raw ore, copper-lead-sulfur mixed flotation, secondary grinding and selection, copper-lead-sulfur separation, lead flotation, and zinc flotation; In the sulfur mixed flotation, the beneficiation agent ethyl butyl mixed with xanthate is used as the collector of copper and lead minerals, and zinc sulfate and sodium sulfite are used as inhibitors of zinc minerals; in the separation of copper, lead and sulfur, sodium sulfite and sodium thiosulfate are used as lead, Inhibitor of sulfur minerals, Z-200 is used as a collector for copper mineral sweeping. Calculated on the basis of 1 ton of raw ore, the first-stage grinding -200 mesh accounts for 75%, and the second-stage grinding is -400 mesh, accounting for 75%. The dosage is 30g, the dosage of zinc sulfate is 1000g, and the dosage of sodium sulfite is 700g; the dosage of sodium sulfite in copper-lead-sulfur s...
