Of the traditional beneficiation methods, the gravity beneficiation method is the most acceptable since chromium minerals differ significantly under specific gravity conditions from waste rock minerals. Flotation of the chrome-containing cake is difficult due to the significant amount of fine waste-rock slurry.
