    Abstract: A method and an apparatus for sorting mined material is based on using a range of options for sensing multiple properties of a mined material on a fragment by fragment basis and then analysing the multiple types of data and making decisions about the classification of each fragment and then sorting the fragment based on the analysis. The multiple sensing options include the response of the fragments to electromagnetic radiation. Other sensing options may include sensors that look at the response of fragments of a mined material to an acoustic wave or a magnetic field or optical sensors that evaluate texture or other surface characteristics of fragments.

    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.
