Metodo para controlar una celda de flotacion por espuma de un circuito de flotacion por espuma para separar sustancias, que comprende maximizar la estabilidad de la espuma por medio del cambio de velocidad de circulacion; y metodo para controlar un circuito de flotacion por espuma.

摘要

A method of controlling a froth flotation cell in a froth flotation circuit for separating substances comprises periodically carrying out a control routine to maximise 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.
