LECTURE NOTES
Scope of Ore Beneficiation: Previously selective mining practices were followed. But after the development of inexpensive ore beneficiation methods, bulk mining practices have proved to be more economical compared to careful selective mining. In a general way the scope of mineral dressing or ore beneficiation is twofold: 1.

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 agglomerated pellets (Iron and …

Titanium Ore Processing and Beneficiation
Crushing of Ti Ore. Conventional two stage open circuit crushing reduces the ore to about ¾" which is good feed to the rod mill. Sometimes a closed circuit reduction becomes necessary to ensure all minus ¾" or finer feed to the grinding circuit. Nature of the ore and its moisture content are factors considered in choosing circuit to be used.
