Reverse flotation separation of hematite from quartz

2019-8-1 · The results evidently demonstrate that the addition of magnetite is beneficial to the selective separation of hematite. A schematic of magnetic seed flotation is shown in Fig. 5. The addition of magnetite has likely two effects on the reverse flotation of iron ore. It acts as a depressant by hindering transfer of fine hematite into the froth.
