This was the first DEXRT 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.
Jul 08, 2018· Of interest, De Beers have also recognized the potential of this technology and have also developed their own sorting machines which are also available on the market, in addition to Tomra and Steinert. As another variant to consider, it is also possible/feasible to install tailored XRT sorting down to 1mm subsequent to a precon DMS.
sorbased sorting," said McKenzie. "Given the strategic importance of electrical power genera tion, coal was identified as a focus area." XRT was then being tested in the process Pilot XRT plant opened at Vlakfontein coal mine One of two XRay Transmission (XRT) ore sorters at Mintek''s recently opened plant at Vlakfontein coal
Dual Energy XRay Transmission (DEXRT) sorting is a recent development in the ... images show a blue coloured simulated DEXRT image. In comparison, coal is .
Coal sorting with an xraytransmission (XRT) sensor has experienced a lot of development since first described by Jenkinson et al. in 1974 Powerful computers and increasingly sensitive Xray scintillation counters enabled the development of highperformance sensorbased sorting machines. The first industrial installation of a belttype XRT sorting for coal has been in operation since 2004.

Mpumalanga, South Africa. The separation of coal and torbanite by conventional gravity separation techniques is often difficult, due to the overlapping densities of torbanite and coal. Preliminary laboratory DEXRT testwork results on high quality coal and torbanite products were promising. In
The sorter improved the coal CV from Mj/Kg to Mj/Kg as well as the sulphur content, which was reduced by half (Fig. 3). Von Ketelhodt says that the results obtained from the test are significant in terms of the potential of XRT sorting for coal mines.
With this method, the decentralised preconcentration 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 DEXRT sorting because it could be used to destone coal (to reduce ash content and create streams with different heating values) and to desulfurize coal (by identifying and rejecting pyrite inclusions).
Jul 18, 2016· One sensortechnology used in SBS is dualenergy Xray transmission (DEXRT) sorting. The principle is known from luggage safety inspections at airports and has already been adapted to the sorting of numerous commodities in the raw materials sector, such as coal, gold ore and tungsten ores.
