Mineral processing - Energy Efficiency Exchange

Why be energy efficient? 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.
