Gold. In southern Africa, two x-ray sorters are used to pre-concentrate sulphidegold oreinto two different grain size categories. While the input material has an averagegoldcontent of less than 0.8 g/t, the sorted product achieves a concentration of more than 4 g/t with an efficiency of approximately 90%.
