Destoning The Moatize Coal Seam Mozambique By Dry Jigging

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-media circuit operates with a ...
