Sep 15, 2005· Flotation cells have three main control parameters. (1) reagent dosing rate (2) froth depth and (3) air addition. rate. Many other parameters may vary such as feed rate, particle. size distribution and head grade, however these are the output. of upstream processes and are not controlled in the flotation. circuit itself.

Since the early days of flotation, process technicians have known that the speed at which the froth is recovered over the lip of the cell has a very direct and consistent influence on the grade and recovery of the circuit. No plant would deny that, even to this day, one of the most important aspects of a process technician's job is ensuring that the froth is moving …

Online monitoring and control of froth flotation systems. Sep 15, 20101.. BackgroundAn understanding of processes occurring in the froth phase has long been held key to understanding the overall behaviour of froth flotation systems (Pryor, 1965, Glembotskii, 1972, Cutting et al., 1986, McKee, 1991, Mathe et al., 1998).The structure of froths …

Self aspirated flotation machines have historically been favored in low technology processing plants, as air addition is one less variable that must be controlled. However with most modern plants having computer based control systems, the ability to accurately control the air addition rate in to the flotation cell gives the operator a
