know moresensor based ore sorting transforms the bottom line in
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 method for a number of deposits.
