However, the flotation performance is difficult to be improved although many reagents and flotation flowsheets have been tested. In this study, some factors that may influence the flotation performance of this ore were tested. The objective of this study is to point out a solution to the flotation problem of low grade lead–zinc sulfide ore. 2.

Since 1936 when lead-zinc sulphide flotation commenced at Mount Isa, at least three types of ore have been encountered.Each ore has presented problems to flotation metallurgists. The three types of ore are, 1. partially oxidized upper level sulphide ore, 2. Black Star ore from the lower levels with its carbonaceous fraction, and. 3.

India. would include a lead-zinc ore, in which the lead and zinc minerals are recovered sequentially into separate flotation grind-size versus recovery, also with timed flotation concentrates.
Flotation Flowsheets - Mineral Processing & Metallurgy. The flow-sheet is of the "secondary" type when flotation is an accessory or subordinate process and some other means of concentration, usually gravity concentration, is the principal method of treatment.
Flotation of synthetic zinc carbonate using potassium ethylxanthate. Int. J. Miner. Process., 11: 79--88. An attempt at flotation of fine grains of zinc carbonate using potassium ethylxan- thate as the collector and sulphydryl and copper ions as the activators has been under- taken.

Froth flotation is again employed to produce marketable concentrates of both. The process is identical in principle to the flotation of other minerals. The figure on the right is a simplified version of a Pb/Zn flotation circuit. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated.

Oxide lead–zinc ore sample containing 10.17% Pb, 10.98% Zn, 57 g/t Ag and 164 g/t Cd was subjected to this experimental study and taken from Kayseri located in the foothills of the Aladag ˘ Mountains, Turkey. Preliminary flotation tests with the ore
With the exhausting of lead–zinc sulphide ores, the recovery of lead-zinc oxide ores becomes more and more significant. Extensive work has been carried out at home and abroad on the treatment of lead and zinc oxide ores in reagent scheme, flotation flowsheets, and joint process. Sliming is one of the main reasons why the lead-zinc oxides are difficult to recover.
