Iron Ore Flotation Process At Brazil

Processes for phosphorus removal from iron ore

Phosphorus can be removed from iron ore by very different routes of treatment. The genesis of the reserve, the mineralogy, the cost and sustainability define the technol ogy to be applied. The articles surveyed cite removal by physical processes (flotation and selective agglomeration), chemical (leaching), thermal and bioleaching processes.

Optimal Control of Iron Ore Flotation with Soft Sensors for Grade and Recovery .

For Brazilian iron ore producers, reverse ionic flotation is preferred to obtain high quality concentrates from silie ores. The SiO2 (silica) particles are rendered hydrophobic by amine (ionic collector) in alkaline conditions, while iron is depressed by the addition of starch.
