Get PriceU.S. Pat. No. 3,779,380 to Bishop describes ore beneficiation and particularly froth flotation applied to iron ore. The beneficiation process described enables direct flotation of the iron oxide. This process, however, is not as efficient when dealing with fine grained ores as is the present process.

Get PriceHowever, the latter beneficiation method is used to handle the fine red ore or mixing ore (namely the mixture of weak magnetic red ore and the magnetite). After the crushing and grinding processes which separate the iron ore monomer, we adopt the gravity separation or the combination of gravity separation and magnetic separation to get high grade fine concentrate.
