iron ore mineral processing methods

Iron Ore Processing: From Extraction to Manufacturing

The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.

Iron ore beneficiation: an overview

Dry processing of iron ore: In dry processing of iron ore, ROM is generally crushed below 40 mm through three-stage crushing and thus segregated by screening into 10–40 and −10 mm fractions. For softer ore, tumbler index is generally low and hence lump ore is crushed below 10 mm to produce fine product. Yield from the plants has …
