02 Reverse flotation of iron ore beneficiation. Reverse flotation process can be used to treat iron ore whose gangue minerals are mainly quartz, which can effectively reduce the silicon content in the concentrate product. Ore dressing plants often use cationic reverse flotation to treat iron concentrate products after magnetic separation.

Pressure oxidation is a process that takes place in autoclaves. It involves a combination of high pressure, acidified ore, high temperature (above 170°C) and oxygen, resulting in the formation of ferrous iron (Fe 2 +), ferric iron (Fe 3 +), sulfate (SO 4 2-) and elemental sulfur (S 0) for pyrite. Alternatively, pressure oxidation has emerged ...
