Jan 15, 2020 In ilmenite plants, the raw ore is classified into coarse (+20 μm) and fine (−20 μm) fractions. The coarse ore can be effectively preconcentrated using conventional magnetic separators [1,12,13], and currently, SLon magnetic separator is being applied well in plants . However studies on fine ore are still being conducted in the start-up stages.
