Control strategies for minerals thickening (part 1)
The way to control the mud/bed layer is by manipulating the speed of the pump or the discharge valve. Standard control strategies. Currently in most medium-sized mineral thickening operations 10 to 50 ktpd, and even large operations greater than 100 ktpd, standard PID (Proportional, Integral, Derivative) control systems are used.
