Abstract: A system and method for dry ablation beneficiation of ore. The system comprises a nozzle to emit an air stream, and a feeder to provide ore particles for entraining in the air stream and colliding. The ore comprises gangue grains bound together with a cementing material. The cementing material comprises a desired material. The collisions are controlled to help preferentially break the cementing material over breaking the bonds holding a gangue grain together. The system also comprises a classifier to separate broken cementing material from the remaining material (which includes gangue grains) based on size. The method comprises entraining the ore particles in an air stream and colliding to preferentially break the cementing material. The ore particles may be collided with each other or a surface. The broken cementing materials are then separated from the remaining materials (which includes gangue grains). The enriched ore is the separated cementing material.

Abstract: A reactor vessel is provided having a solids feed opening for particulate graphite and a product outlet for purified particulate graphite. The vessel has an interior volume for containing the graphite particles, with a plurality of gas feed openings at the bottom of the interior volume, near the centre-line, for feeding of chlorine-containing gas, wherein the chlorine-containing gas passes through the particulate graphite, fluidizing the particulate graphite. Electrodes are provided which function to heat the particulate graphite, as it is carried upwards under the fluidizing effect of the centrally injected chlorine-containing gas. When the heated graphite particles react with the chlorine gas, purified particulate graphite is formed and may be extracted through the product outlet.
