  • Recovery of Copper from Industrial Waste Water by Foam

    finer an ore is ground, the greater the energy that is required, so it makes sense to fine grind only those particles that need fine grinding. Complete liberation is not required for rougher flotation, only sufficient liberation to release enough gangue from the valuable mineral to get a high recovery.

    The invention provides method to recover, by means of froth flotation, a desired metal value from a feedstock containing it. In a comminution step, the feedstock is comminuted using comminuting media of an iron and chrome steel alloy comprising from 12% to 30% chrome. In a conditioning step, the feedstock material is contacted with thiourea and/or oxalic acid as primary flotation reagents.
