US5307938A Treatment of iron ore to increase recovery

The described invention relates to the processing of iron ore, particularly taconite ore. In particular, the invention relates to the separation of the iron containing component from the silicious and other gangue components such as phosphorus compounds in low grade iron ore. Typically, the separation is accomplished by a flotation process to remove the gangue to recover the iron component.
