Iron ore sample found is a part of banded iron ore formation. Hematite and goethite are major constituents of iron ore samples. Hematite in the ore sample occurs as specularite with inter granular micro-pore spaces. Goethite is profuse and occurs as colloform product in cavities in addition with the weaker bedding planes.

Spirals require addition of water at various points down the spiral to assist washing of the iron ore, i.e. transporting away the light gangue from the dense ore. The amount of wash water and its distribution down the spiral trough can be adjusted to meet the operating requirements.

The ore proper can usually be separated by crushing the raw ore and simply washing away the lighter soil. Breaking down the ore proper is more difficult, however, as it is a chemical compound of carbonates, hydrates, oxides, silicates, sulfides and various impurities.

The ore proper is separated by crushing the raw ore are simply washing away the lighter soil. Breaking down the ore from its impurities is more difficult. This is achieved through a processed called smelting. Smelting involves heating up the ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. This

Producing iron by this method is rather inefficient. The yield from the best ore rarely exceeds 50% of the iron found in the ore. Ordinarily the yield is on the order of 20% and the remaining iron is lost in the slag. Iron ores range in composition, depending on where it is mined from around the world.

The frothed ore collects on the oil section whereas the impurities settle down in the water medium. Chemical Separation: One way of concentrating the ore is by chemical separation. For example, the separation of aluminium (Al) from the bauxite ore. This process of separating aluminium from the bauxite ore is also termed Bayer’s Process.
