Depressants and dispersants , Iron sulfide (pyrite, pyrrhotite, marcasite) depressant used in the flotation separation of base metal sulphid Also used as an alternative partial cyanide replacement to depress iron and zinc sulfides in Pb / Zn flotation , When processing complex ores their purpose is to prevent aggregation of fine and.

The number one depressant is reagent starvation In polymetallic ore pyrrhotite does not compete very well for collectors, and the use of starvation dosages is far more effective than trying to depress pyrrhotite once it has been activated.

The ore is then ground to -100 mesh in ball mills Using wet magnetic separators the magnetic ore is separated (pyrrhotite) and further reduced to -200 mesh in a ball mill Classification is accomplished with screens and cyclon The pyrrhotite is then sent to froth flotation cells, and produces a.

Pyrrhotite is one of the most abundant sulphide gangue minerals in base metal mining operations It has little economic value and is a significant contributor of SO 2 emissions at the smelting stage, thus it is rejected in most concentrators, requiring a concerted effort to ensure it is well separated from valuable minerals The mineral processing of pyrrhotite is generally understood, however.

Abstract Pyrrhotite (Po) is one of the most abundant sulfide minerals in processing industry and must be rejected in most cas Particularly, Po rejection and its selectivity against pentlandite (Pn) have long been a challenge due to similarities in the mineral composition of the two minerals and the collectorless flotation characteristics of Po.
