Mineral processing is the process of separating commercially valuable minerals from their ores in the field of extractive metallurgy.^[1] Depending on the processes used in each instance, it is often referred to as ore dressing or ore milling.

Beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (ore concentrate) and a waste stream (tailings). There are many different types of beneficiation, with each step furthering the concentration of the original ore.
