Apr 03, 2014· This process is primitive and widely used in lumpy iron ore processing to dislodge and remove friable and soft lateritic materials, fine materials and limonitic clay particles adhering to the ore. Wet scrubbing is also useful in hard and porous ores, which invariably have cavity/pores filled with clayey material that need substantial removal.

4.1.2 Iron Ore Beneficiation Iron ore occurs naturally in a variety of forms, from sandlike iron fines to solid rock masses. Crude ore, or ore mined in the natural state, seldom occurs in a pure state and requires some form of beneficiation. Crude ore is commonly mixed with other minerals (gangue), which reduce the iron content.

Apr 19, 2016· Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior in grade to direct shipping ores. Low grade deposits containing specular hematite (Fe2 O3) as the major iron mineral as low as 25% Fe can be treated with SubA Flotation to produce concentrates that average better than 62% Fe with less than 9% SiO2

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.
