With this method, the de-centralised pre-concentration of coal in small, remote mines allows the coal to be separated from the waste rock, to immense economic advantage. Transport costs are massively reduced, or the coal is sold directly as a high quality product. The use of drum screens is very common in coal beneficiation.
May 15, 2016· Coal operations were one of the earliest adopters for DE-XRT sorting because it could be used to de-stone coal (to reduce ash content and create streams with different heating values) and to desulfurize coal (by identifying and rejecting pyrite inclusions).

•X-Ray transmission sorting has particular promise in the field of dry coal sorting. For other silicate minerals, the current top size that the X-rays can pass through is around 40mm •The RadosX-Ray fluorescence sorting technology, developed and operated .
Coal sorting with an x-ray-transmission (XRT) sensor has experienced a lot of development since first described by Jenkinson et al. in 1974 Powerful computers and increasingly sensitive X-ray scintillation counters enabled the development of high-performance sensor-based sorting machines. The first industrial installation of a belt-type XRT sorting for coal has been in operation since 2004.
Dual energy X-ray transmission sorting of coal by L. von Ketelhodt* and C. Bergmann† Synopsis Dual energy X-ray transmission (DE-XRT) sorting is a recent development in the range of sensor-based sorting technologies available today. DE-XRT is particularly suitable for dry coarse coal beneficiation in the size range -120 mm +12 mm. In this ...

This was the first DE-XRT sorter available in South Africa, and was housed at Mintek in Johannesburg. A 150t sample was provided from a box cut adjacent to the coal deposit under investigation in order to conduct bulk and pilot sorting tests, the focus of which was on obtaining coal products of low ash and torbanite content.
