When theiron oreis extracted from the mine, it must undergo severalprocessingstages. Six steps toprocess iron ore. 1. Screening. We recommend that you begin by screening theiron oreto separate fine particles below the crusher’s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.Get Price
Iron oreminerals, particularly hematite and goethite, are beneficiated by a combination of size fraction, preconcentration, and flotation in stages (Fig. 13.45).Iron orerequires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe.
