Sensor-based ore sorting transforms the bottom line in gold mining Exploring gold ores becomes more challenging every year. Mines increasingly deliver lower grades and complex mineralogy, forcing mills to process more material and thus compounding the expanding ratio between these tonnages and the ounces of ore produced.

Ore sorting is a mineral concentration process where individual ore particles are separated from the unwanted material based on some physical (or chemical) property. Ore Sorting can be used for: Pre-Concentration / Waste Rejection. Ore-type diversion. Concentration to product. Sensor Based Sorting is the automation of this process Long History.

Due to the low concentration of gold, ore sorting for gold has always required measuring indirect properties, such as density or colour, to allow separation on a rock by rock basis. This only works on an ad hoc, by deposit basis and is likely to be least reliable where it is most required in low grade ores. One candidate technique, Gamma Activation Analysis

· The sorting belts run at 25 ft. per min., and on an average 40 native boys pick about 60 tons per hour of waste and tube-mill pebbles. In 1946 the waste amounted to 2.05 per cent of the crude ore and had an average value of 0.152 dwt. per ton. The cost was 13.06d (21.8 cents) per ton of waste.
