Metallurgical ContentOpen Circuit GrindingClosed Circuit GrindingGrinding Circuit Process Control VariablesGrinding Operating Costs The simplest grinding circuit consists of a ball or rod mill in closed circuit with a classifier; the flow sheet is shown in Fig 25 and the actual layout in Fig 9 This single stage circuit is chiefly employed for coarse grinding when a product finer than 65

Where the SAG mill/ball mill circuit is the bottleneck in the processing plant the pebble circuit can be a significant factor in limiting overall plant capacity The pebble circuit recirculating load can be very significant depending on the ore characteristics and SAG mill operating dynamics

Run of mine ore milling circuits are generally difficult to control owing to the presence of strong external disturbances poor process models and the unavailability of important process variable meas urements These shortcomings are common for processes in the mineral processing industry For

The paper advocates the use of MPC for mineral recovery processes It is argued that MPC is able to provide a quality of regulatory control that cannot be matched by PID control or expert system control The superior performance of MPC in controlling challenging loops provides a clear benefit in terms of plant profitability

Mineral processing can involve four general types of unit operation comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation In all of these processes the most
