Mineral processing Energy EXchange

Valuable minerals are extracted from rock via the process of comminution (crushing and grinding). This process can be further refined using various means of separation, such as froth flotation, optical sensors and centrifugal devices. The comminution phase can consume more than 50% of the total energy used in a mining operation.
