The basic process flow sheet consists of primary and secondary crushing and screening circuits feeding HPGRs for dry comminution. After cobbing, the liberation of the iron bearing mineral (magnetite) is completed in a wet grinding circuit. Concentration stages include besides cobbing, roughing and finishing with low intensity magnetic separators.
The taconite extends the entire NE-SW extent of the Property, 2.2 km and beyond, and occurs over a width of 800 m to 1 km in a NW-SE direction. The taconite is folded and its true thickness varies throughout because of tectonic thickening, erosion and possibly the original basin topology.
