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.
