Flotation has been used for iron ore beneficiation since 1950.The first two systems in Michigan were built for direct flotation, Tall oil and diesel oil were added as collectors. Today were built indirect flotation process. This process uses amines as flotation agents to eliminate most of the remaining silica and thus reach a high Fe content ...

Dephosphorization of iron ore can be achieved through bioleaching. Different methods are needed to remove phosphorus from iron ore depending on whether it is present as a mineral (apatite) or associated with iron minerals (Edwards et al., 2011). Although most phosphorus occurs entrapped within goethite in Australian iron ores, a considerable ...
