Metal grade is used to give an idea about the removal of gangue minerals and removal of oxygen or sulphur. For example mineral grade of pure (A is unity but metal grade (or iron grade) of pure mineral (A is 70% which means 30% oxygen has to be removed to get iron.

Selective smart blasting, oresorting and waste removal can be used to increase ore grade ahead of crushing or grinding by removing coarse waste material (gangue). The CRC ORE at the University of Queensland has shown that it is possible to achieve as much as a fold increase in average mineral ore concentration feed to the grinding mill through using smart blasting, ore sorting and gangue rejection.
Grinding Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type.
