Chrome Beneficiation
Chrome beneficiation begins with a series of sizing screens. Hammer samplers are used to sample each stream, while Over Belt Magnets are used to remove ferrous junk. The last sizing screen provides three aggregated ore streams. The dewatered chrome waste is sampled and can be sent to client/DMS or rod milling.
