Beneficiation of South African chromite tailings using ...

2020-7-27  Chromite recoveries is a major concern particularly in processing of finely disseminated ores due to its inherent complexities. The gravity separation process is the main beneficiation process used to recover chromite mineral. However, these conventional chromite processing techniques become inefficient and complex when treating fine and ultrafine size particles (less than 75µm) leading to losses [1, 2]. Apart from that, separation of chromite from other associated minerals is sometimes very difficult owing to the complexity of ore texture along with presence of near density minerals. In chrome ore beneficiation, specific gravity and size-based separations are the most convenient and cost-effective methods [3, 4]. Majority of chromite ore
