    Quartzassociated Gold Sorting Tomra

    Whenever sulphide or quartz is associated with gold, the resultant gold ores are typically amenable to a certain degree of particle sorting. And in the case of the complex blend of quartz associated with gold, the pre-concentration of the ore by means of sensor-based ore sorting during the early stages of the production process can be effected by harnessing the scattering effect of a LASER beam.
