huge money is saved on freight by transporting upgraded ores. 4. Reduced losses of metal at the smelter: ... general way the scope of mineral dressing or ore beneficiation is twofold: 1. It helps in eliminating unwanted chemical species from the bulk of the ore. 2. It helps in eliminating particles improper size and physical structure which
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 …

Mineral beneficiation is the process of concentration, and was first described in Agricola's famous treatise, De Re Metallica, published in 1556. The earliest ores to be discovered and processed were of such high grade that they did not require beneficiation, and they satisfied mankind's needs for nearly 3,000 years. ...
