Following floatation simulations, a second David Tube test was completed on the tails from each composite to confirm the amount of recoverable magnetite from Fe after copper had been extracted. The results of the froth floatation tests on the composite samples demonstrate that copper may be economically recovered.

the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation route.

It is also used to concentrate magnetite (Fe3O4), chromite (FeCr2O4) and pyrolusite (MnO2) from unwanted gangue. Froth Floatation Process The principle of froth floatation process is that sulphide ores are preferentially wetted by the pine oil, whereas the water wets the gangue particles.

The adsorption mechanism of mixed cationic C 12 amine and anionic sulfate / oleate reagent schemes was examined through Hallimond flotation studies using pure quartz and hematite minerals. The flotation response of both quartz and hematite with cationic and anionic collectors in isolation and with mixed cationic / anionic collector systems was evaluated as well.
