Decentralized Control of a Pilot Flotation Column: A 33
Abstract This paper details the application of a decentralized control strategy to a pilot flotation column working with a water air system. The process is represented by a multivariable system composed of three inputs and three outputs. The selected control variables are the froth depth, air hold up and bias rate whereas the corresponding manipulated variables are the set points of

Automatic control of a laboratory flotation column
Abstract The operation of industrial flotation columns requires the control of at least two variables, the interface position and the bias rate, by manipulation of some appropriate operating variables. Problems arise due to the reliability of existing methods of measuring the bias (i.e bias = tailings water feed water), a situation which has often forced the industry to disregard this
