MEASURING FROTH STABILITY

摘要

A method of measuring froth stability (as described herein) of a froth in a cell of a flotation circuit for a slurry of a mined mineral containing valuable material and gangue materials is disclosed. The method includes a step of measuring one or more than one froth stability parameter using a measurement column arranged to extend downwardly through the froth in the cell to a location below an interface between the froth and the slurry in the cell. A method of controlling the operation of a flotation cell that is based on the froth stability measurement method is also disclosed.
