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

Geology of Gold Mineralization & How Gold Deposits are FormedThe results are reported as troy ounces of gold or silver or both per short avoirdupois ton of ore or as grams per metric ton of ore. Placer deposits represent concentrations of gold derived from lode deposits by erosion, disintegration or decomposition of the enclosing

When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
