AN INVESTIGATION OF FLOTATION REAGENTS

In flowsheet #3, the flotation feed is first sized at 48 mesh (or somewhere between 35 and 48 mesh). The coarse feed is subject to one-step flotation, while the finer feed is processed using a straight rougher-cleaner flowsheet. Flowsheet #4 was developed based on the fact that in rougher flotation, phosphate floats first with the
