Flotation of CopperLeadZinc Ores ResearchGate
Copper minerals flotation cycle is especially sensitive to selectivity and sometimes there is a higher content of lead and zinc minerals present in copper concentrate which is penalizedSequential Copper–Lead–Zinc Flotation To improve the selectivity between copper and lead, a sequential copperleadzinc rougher circuit wasSequential Copper–Lead–Zinc Flotation

Which flotation scheme used in the differential copperlead bulk concentrate separation is generally and often dependent upon which mineral has the greater mass in the bulk concentrate Whichever mineral constitutes the lower bulk concentrate mass will be floated away from the other mineral which is depressed for flotation selectivity reasonsResults of numerous studies involving pure minerals, their mixtures, and ores floated on a laboratory and industrial scale indicate that the separation of copper and lead minerals by flotation is possible The list of depressants used to facilitate separation includes cyanide, dichromate, FeSO 4, SO 2 (Table 1), and polysaccharides (Table 2)Removal of lead minerals from copper industrial flotation

Oxidic ore can be concentrated using flotation or, if it has a low acid demand, it may be economic to acid heap leach the stockpile The recovery of these copper minerals by flotation orBulk copper/lead flotation is performed at natural pH using a NaSNaCNZnS04 depressant system, combined with sodium isopropyl xanthate as the collector The bulk rougher concentrate is cleaned three times before copper/lead separation, using the flowsheet shown in Figure 6 The zinc circuit is a standard limeCUSOq circuit with xanthate collectorDevelopment and introduction of a new copper/lead
