All of these terms can be used interchangeably but refer to the process of separating usable minerals from the low-value minerals in ore known as gangue. What is Mineral Processing? Beneficiation falls into two categories, wet and dry. Wet beneficiation, or wet grinding, based on mineral density, combines with froth flotation to reduce particle ...
Ball or rod mills crush and grind the mined ore to fine particles that may be only microns (10-3 mm) in diameter, releasing molybdenite from the gangue (worthless rock). The grinding mills on the right reduce rocks the size of soccer balls to the size of gravel. Further ball milling reduces the material to the consistency of face powder.
The crushing and grinding operations are an important part of the processing of mineral resources, and it is also operation with high investment and high energy consumption.
