After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: Ratio of concentration % Metal Recovery % Metal Loss % Weight Recovery, or % Yield Enrichment Ratio Table 1: Grade/recovery performance of a hypothetical copper ore flotation process.
Lead sulﬁde ore, especially galena, is the main raw material for lead production, because of its good natural ﬂoatability 24. However, with the increasing consumption of lead metal, the resources of lead sulﬁde cannot meet the continuing high demand, so the exploitation and utilization of lead oxide ore is imperative. The lead oxide ...
In the mineral processing industry, lead zinc sulfide ores are usually processed by froth flotation to enrich the purpose minerals 1. Flotation is a complex process, and the selective separation of minerals depends on the balance between the hydrophilic species and hydrophobic species on the mineral surface 2, 3.
Flotation machines are subject to coarse separation, swept separation, fine separation and floatation, so the useful ore are reclaimed. Gold lead zinc copper ore beneficiation plant US $1000 $100000 / Set

The flowsheet above was designed to treat economically approximately 200 tons in 24 hours of a low grade dump ore containing lead and zinc values as well as some silver in both sulphide and oxide form.
The separation of copper bearing from zinc sulphides is effected by two stage selective flotation, the zinc minerals being depressed and the copper minerals brought up in the first stage with reagents similar to those required in the lead flotation section of a lead zinc plant; the zinc sulphides are floated in the second stage in the ordinary way. The ores treated by this process are mainly those containing chalcopyrite, sphalerite, and marmatite in a very pyritic gangue.
Copper Lead Zinc ores. The Cu Pb Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage. In this case, as a general rule because both copper and lead minerals tend to float well, these are usually the target bulk flotation minerals.
