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. The other two underflow chrome ...
INTRODUCTION Chromite (Fe,Mg)(Cr,Al) 2O 4 is a paramagnetic mineral that occurs as a gangue mineral associated with platinum group metal (PGM) orebodies in the western limb of the Bushveld Complex. Chromite grades vary between 3–5% in the Merensky Reef and the Platreef, and 5–15% in the UG2 reef (Engelbrecht, 2012).
Introduction:this technology is magnetic-gravity combined separation technology. Weak magnetic separation can hardly be separated with chrome minerals in coarse grains, which leads an unideal gravity separation index. In order to recover high-grade chrome concentrates, weak magnetic concentrates should be grinded.
