Destoning the Moatize Coal Seam, Mozambique, by Dry Jigging

31.08.2020  This paper proposes pre beneficiation studies by air jigs of the coal layers from a Moatize coal deposit. Pre beneficiation, also called destoning, removes tailings before the beneficiation plant. The air jigs operate in the same granulometric size range as the heavy media cyclones HMCs that are installed in the preparation plant. With the destoning, the heavy
