    Abstract: 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.

    Abstract: A method of sorting mined material to separate the mined material is disclosed. The method comprises exposing particles of the mined material to microwave energy and heating the particles depending on the susceptibility of the material in the particles. The method also comprises thermally analyzing the particles using the temperatures of the particles as a basis for the analysis to indicate composition differences between particles. The thermal analysis step includes thermally assessing particles against a background surface. The thermal analysis step also includes heating the background surface to a temperature that is different to the temperature of the particles to provide a thermal contrast between the particles and the background surface. The method also comprises sorting the particles on the basis of the results of the thermal analysis.

    Abstract: A method of sorting mined material to separate the mined material into at least two categories is disclosed. The method comprises exposing particles of the mined material to microwave energy and heating the particles depending on the susceptibility of the material in the particles. The method also comprises thermally analyzing the particles using the temperatures of the particles as a basis for the analysis to indicate composition differences between particles and then sorting the particles on the basis of the results of the thermal analysis. The method also comprises compensating for temperature variations in the mined material that is supplied to the method.

    Abstract: Se da a conocer un método de control de una celda de flotación con espuma en un circuito de flotación con espuma para separación de sustancias. El método incluye controlar el caudal de gas de flotación a la celda basado en cambios en las condiciones de la celda para mantener la operación de la celda a una estabilidad pico de la espuma de la celda o más próxima a la estabilidad pico de la espuma de la celda que si no se cambiara el caudal de gas de flotación.
