Guo et al. reported that the recovery of copper and iron can be improved by a modification process of molten slag with addition of complex additives. The 72% copper and 64% iron recoveries can be achieved by a combined flotation and magnetic separation process subsequent. Undoubtedly, flotation is an effective route to recover valuable metals.
Therefore desliming increases flotation efficiency, but results in a large volume of tailings and in loss of iron to the tailings stream. Dry processing of iron ore presents an opportunity to eliminate costs and wet tailings generation associated with flotation and wet magnetic separation circuits.

The five basic types of reagent used in froth flotation recovery include collectors, frothers, depressants, activators and modifiers. When designing the processing plant, the types and quantities of reagents used should be considered together with any depressing requirements to lessen environmental impacts in the tailings streams (Ritcey 1989).
In order to design the copper flotation circuit you should analyze the CuOx/Total Cu ratio to determine the impact of the copper oxidation on the copper recovery by flotation. Sometimes, the degree of oxidation is minimum, and the design should be focused on the copper sulphides. Copper flotation tailings can be fed to the primary magnetic ...
