A BrainWave controller was used on the flotation cells (Fig. 5.1.4), which uses the cell levels and cell valve positions to estimate the flow between the cells. These flow estimates are usedas feedforward inputs to the BrainWave controller to improve the rejection of level disturbances caused by the actions of the upstream controllers.

3. Principle Of Operation Froth flotation commences by comminution (that is, crushing and grinding), which is used to increase the surface area of the ore for subsequent processing and break the rocks into the desired mineral and gangue in a process known as liberation, which then has to be separated from the desired mineral. The ore is ground into a …
