Gold Ore Sorting : TOMRA

Gold ores are typically amenable to sensor-based ore sorting to some degree, and this is usually accomplished with XRT or laser sensors, or a combination of both. A two-step sorting flow-sheet consisting of an XRT rougher plus a laser scavenger (or alternatively, a laser rougher and an XRT scavenger) has already proved an optimal recovery ...

Quartz-associated 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.
