Introduction To Mineral Processing
Mineral processing is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. Although the primary operations are comminution and concentration, but there are other important operations in a modern mineral processing plant, including sizing, sampling and ...
Unit Operations in Mineral Processing
Grinding is by far the most energy-demanding operation in a minerals processing plant!!! Represents more than 50% of the total energy consumed in the plant. Operation of the mill should produce an economic optimum particle size. Milling circuits are used to optimize grinding, thus classification is of high importance.
