Iron ore beneficiation: an overview

The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and …

Beneficiation of bauxite

A primary objective of the beneficiation process is to reduce the silica content in the ore, as the latter reacts with caustic soda during the digestion step to precipitate out as insoluble sodium aluminium silicates, e.g. 2Na2O.2Al20;,.3Si02.2 H20. This salt is eliminated from the process along with the insoluble iron and
