In practice ores are ground to an optimum grind sie determined by laboratory and pilot scale testwork to produce an economic degree of liberation. The concentration process is then designed to produce a concentrate consisting predominantly of valuable mineral with an accepted degree of locking with the gangue minerals

Dec 02 2005nbsp018332Taken together these represent one of the worlds largest industries. Liberation of the value minerals from the ore matrix is a significant undertaking as is the disposal of the gangue materials or tailings once processing is complete. Materials handling is a significant problem in minerals processing as is process or plant control

Introduction to Mineral Processing. The crushed copper ore containing for example 0.75 Cu and 0.015 Mo is fed to the grinding circuit where water is added and the ore is ground to the proper sie. Lime and an oil for collecting molybdenum are usually added in the grinding circuit. a concentration factor of 3 to 10 times is typical
