The salt extraction process: a novel route for metal ...

AbstractThe present work is part of an investigation towards the development of a process route for the extraction of metal values from slag, low grade ores and other oxidic materials such as spent refractories using molten salts in the temperature range 800–950°C. The present paper focuses on the recovery of metal values, primarily Cr and Fe, from electric arc furnace slag and chromite ore.

Separation and Concentration | Mineral Processing ...

Dense Media Separation (DMS) is an enhancement of gravity situation in which ore is fed into a solution with a density between those of the mineral and gangue, respectively, with one product rising toward the surface for collection and the other being discharged at the bottom of the vessel. Coal and chromite are often collected by this means.
