The first stage is the removal of iron as a solid residue in the form of either jarosite (a basic ferric sulfate) or the oxides goethite or hematite. This is then followed by cementation with zinc dust to remove other metallic impurities (including copper, nickel, cadmium, cobalt, and germanium) from the solution.

Extraction. Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines.
