What Is a Mineral? Definition and Examples
The word mineral comes from the Medieval Latin word minera, which means ore or mine. Several thousand minerals are known. Of these, around one hundred are components of rocks. A mineral is a natural solid with a defined chemical composition and crystalline structure. Most minerals are inorganic and form from geological processes.
Mineral Processing
Haldar described mineral processing «as the value-added processing of raw material (run-of-mine ore) to yield marketable intermediate products (e.g. copper concentrate) or finished products (e.g. silica sand) containing more than one valuable minerals and separation of gangue (tailing).»The run-of-mine components consist of the …
Mineral Processing
mineral composition, meaning that they should be of only one type. This implies that the break should take place primarily at material transitions within the solid, i.e. at an ore's grain boundaries. Various physical and chemical sorting techniques can be used to separate the resulting mixture into concentrate (high ratio of the value mineral)

Ore Dressing
If the particles are too large, unwanted accessory minerals cannot be separated from the ore. The ore concentrate obtained only has a low purity. Overgrinding, on the other hand, results in high milling costs and low throughput as well as an increased need for chemicals in flotation. Furthermore, flotation cells are sensitive to solid overloading.
APPLIED MINERALOGY IN ORE DRESSING
