Method for flotation of sulfide zinc bearing ores |
| abstract |
FIELD: benefication of minerals. SUBSTANCE: method for flotation of sulfide zinc bearing ores includes pulp conditioning with agents/regulators such as calcium oxide and copper sulfate, collecting agent, and foaming agent, and extraction of zinc concentrate in foam product. FS-413M polyelectrolyte produced from reaction of polyethilenepolyamine and thiourea is injected as additional agent/regulator in the process of conditioning. FS-413M polyelectrolyte consumption is maintained within 10 to 30 g/t(ore). EFFECT: highly productive benefication. 2 cl, 1 tbl |
