Abstract (en)
[origin: WO2020188379A1] A process (10, 200) for recovery of chromite fines from a slurry includes feeding a feed slurry (68) comprising chromite fines to a wet spiral concentrator stage (14) comprising a plurality of wet spiral separators or wet spiral concentrators (32), separating the slurry (68) by means of the wet spiral separators or concentrators (32) into a higher-grade chromite slurry (74), a lower-grade chromite slurry (76) and a first tails stream (78), magnetically separating the lower-grade chromite slurry (76) in a wet magnetic separation stage (24) into a magnetic material stream (80) and a non-magnetic material reject stream (86), and separating the higher-grade chromite slurry (74) and the magnetic material stream (80) in a shaking table stage (18) into a chromite concentrate (90) and a second tails stream (92).
