II. IMPORTANCE OF MINERALOGY IN MINERAL

2012-8-10  From mineral processing point of view, it is important to identify the ore and gangue minerals (mineralogical study), their textural relationship (grain size, grain boundary relationship etc.). The mineralogical study also helps in the modal distribution of ore and gangue minerals which decides the grade of ore. Grain size of the minerals and their textural relationship helps in deciding the size reduction and liberation in mineral processing. An effective liberation of gangue minerals and ore minerals
