A review of froth flotation control

2011-9-14 · Advanced flotation control. AFC, also known as stabilising control, aims to reject the effects of input disturbances (e.g. a change of ore type) and maintain the flotation process as close to steady state as possible (McKee, 1991, Laurila et al., 2002). This is generally achieved by controlling mass pull; recycle load; stream grade and/or ...
