The mixed size fractions of either galena orpyrite mineralwere transferred to a 600 mL bottom-stirredbatch flotation celland thecellwas made up to volume with synthetic plant water. Impellor speed was kept constant at 1200 rpm. Theflotation experimentswere performed at the natural pH of the system which was around pH9.

Copper and Pyrite Separation by Selective and Sequential

A copper-pyritemill in Canada uses the 12-cellNo. 21 “Sub-A”FlotationMachine, shown above, for roughing, and a 2-cellNo. 21 “Sub-A”FlotationMachine for cleaning to produce a fairly coarsepyriteconcentrate ranging from 50-62% minus 200 mesh. Feed at the rate of 230-240 tons per day comes from the tailings of a zincflotationunit.

During the batch flotation experiments, the pH varied between 6.5 and 7, while in the continuous tests it varied between 7 and 7.8.Dissolved oxygenwas manually monitored (YSI, Mod. 5739) both in theconditioning tankand in the flotation cell. Temperature was monitored with an ATC probe connected to theOrion SA720 instrument.

Two-Stage Flotation: It was observed in thesingle-stage flotationkineticsexperimentswith the plant samples that about 5 to 12% of magnetite reported to the froth depending on the grade of magnetite after 4 minutes. Therefore, cleaning of the froth product was deemed necessary to reduce the magnetite losses and to obtain a reasonable clean ...

Oxidative leaching of metals byThiobacillus ferrooxidanshas proven useful in mineral processing. Here, we report on a new use for T. ferrooxidans, in which bacterial adhesion is used to removepyritefrom mixtures of sulfide minerals duringflotation.Under control conditions, the floatabilities of five sulfide minerals tested (pyrite, chalcocite, molybdenite, millerite, and galena) ranged ...
