Abstract
Official abstract text for this publication.
A method of controlling a froth flotation cell in a froth flotation circuit for separating substances comprises periodically carrying out a control routine to maximize froth stability during the operation of the cell. The control routine comprises changing the gas flow rate to the cell in a series of steps and assessing the froth stability at each gas flow rate and continuing the step changes in the gas flow rate until the froth stability is a peak froth stability or is within a predetermined range of the peak froth stability of the cell.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of controlling a froth flotation cell in a froth flotation circuit for separating substances, the method comprising carrying out an ongoing control routine to maximise froth stability during operation of the cell to ensure that froth stability is maintained at a maximum during the operation of the cell, the control routine comprising changing the gas flow rate to the cell in a series of steps and assessing the froth stability at each gas flow r…
