Iron ore is an important raw material for steel producers, generally less than 50% grade iron ore can be smelting for use after beneficiation. Iron ore is also used as a catalyst for ammonia (pure magnetite), natural mineral pigments (hematite, limonite), feed additives (magnetite, hematite,) and valuable constructive criticism (magnetite) and the like.

Iron ore fines are characterized on a physical basis by variations in particle size, shape, density, porosity, surface area, roughness, and wettability. Furui et al. (1977) divided iron ore particles into nucleus particles of + 0.7 mm size, intermediate particles of − 0.7 + 0.2 mm size, and adhering particles of − 0.2 mm size.

called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate (enriched portion) containing most of the ore minerals and a tailing (discard) containing the bulk of the gangue minerals.

After beneficiation iron ore availability can improve by about 50%. Steel community and the country demand technological solutions for utilising low grade ores. The technology task that would be imperative: 1. Utilisation of low grade iron ores after beneficiation. 2. Reduction in slime loss by recovery of iron values from slimes. 3.

Processes for Beneficiation of Iron Ores Iron is an abundant element in the earth’s crust averaging from 2 % to 3 % in sedimentary rocks to 8.5 % in basalt and gabbro. Because iron is present in many areas, it is of relatively low value and thus a deposit must have a high percentage of metal to be considered ore grade.

Direct-shipping iron-ore (DSO) deposits (typically composed of hematite) are currently exploited on all continents except Antarctica, with the largest intensity in South America, Australia and Asia. Most large hematite iron-ore deposits are sourced from altered banded iron formations and rarely igneous accumulations.
