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 pre-con DMS.
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.
Cleaning Coal at the Speed of Light Hand sorting was historically a common practice for ores and coal. First radiometric sorter in 1946. Photometric sorter developed in 1952 was the basis of the first commercial sorters in uranium. Around 35 ore sorters worldwide .
The sorter improved the coal CV from 17.9 Mj/Kg to 25.0 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.
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 DE-XRT testwork results on high quality coal and torbanite products were promising. In
•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 .

Sensorbased ore sorting is the terminology used for sensorbased sorting in the mining industry. It is a coarse physical coarse particle separation technology usually applied in the sie range formm 0.3.
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.
