Ferrochrome production using SBS-SAF process technology (Basson and Daavittila, 2013). Chromite concentrate is wet ground to 80% passing 0.075 mm in a ball mill. The chromite concentrate slurry from the mill is filtered using a ceramic filter to bring the moisture content of concentrate to ca. 8.5–9.5%. It is then mixed with a binding agent ...
