— 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 …
The Mined copper ore is initially crushed, milled and concentrated by ore beneficiation process into a fine, gray powder called copper concentrate. If the nature of ore is sulphide, froth floatation process is adopted to do the beneficiation wherein the 1 % copper containing ore is converted to more than 25 % copper containing concentrate.
