Visual information model based predictor for froth

2009-3-1  Regarding the flotation process, it is widely known that the color, morphology and speed of the froth are closely related to mineral concentrations, process status and recovery, respectively. As a consequence, operators often make operating changes based on the visual appearance of the froth as well as past experience.

Common Questions About Froth Flotation Process

2019-4-17  Froth Flotation process flow back to top. The froth flotation process mainly includes grinding, slurry adding, froth flotation separation and dehydration of foam products and tailing products after froth flotation. Before the flotation operation, the ore needs to be ground to an optional size range by the grinding mill, generally less than 0.1 mm.
