    edelmira lvez, luis cisternas, in computer aided chemical engineering, 2014 introduction. flotation circuits are a common technology for the concentration of a broad range of minerals and wastewater treatments. froth flotation is based on differences in the ability of air bubbles to adhere to specific mineral surfaces in a solidliquid slurry.schreiber says that process control in a flotation plant normally can be onerous with controlling slurry level and froth proving inherently difficult in a row of flotation cells. the slurry level in any cell affects the driving head in adjacent cells and this can easily create unstable control conditions.
