- Wet Magnetic Separator For Iron Ore
Alternatively, WHIMS processes (WHIMS = Wet High-Intensity Magnetic Separation) are used. The fine ore from the underflow is sent on the other hand to a spiral classifier, where density separation of the metal ore and gangue taking place in several stages. For even higher iron yields, flotation can be installed downstream of classification.
