01.05.2013· In the Candiota Coalfield, RS, Brazil the Candiota Superior and Inferior coal seams are at current time being mined for power generation. The current study characterizes the other seams of the deposit, which include the upper (S2–S9) seams, the Banco Louco (BL) seam and the lower (I1–I5) seams, which up to date have not been considered for power

Beneficiation of the lower seam coals in the existing washery circuits (2 or 3 product) does not yield requisite quality demanded by the steel sector of the country and as a result it is termed as Non-Linked Washery (NLW) colas, and the entire production of inferior coals is diverted to the thermal power sector, thus, wasting the scarce coking coal resources.

As part of our R&D efforts, HRCM is investing in research to develop X-Ray Transmission (XRT) for dry beneficiation to separate coal from non-coal bearing materials. Ultimately, this will make coal handling and screening more efficient. We've been undertaking XRT dry beneficiation research since 2015. Together with a modified mine plan, XRT aims to allow lower bearing coal seams to become
