Taconite was essentially one rock which was drilled and blasted to get small enough chunks to load in those huge Euclid trucks. It then went through a couple jaw crushers, a rod mill, and a ball mill to get a powder which was 200 mesh. Once one got to that mesh size the silica and hematite were pretty much separate particles.

Rod mills, how they function

Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh). Grinding action is by line contact between the rods extending the length of the mill. Rods tumble and spin in roughly parallel alignment simulating a series of roll crushers. This results in preferential grinding of

Modelling the processing of gasifier feed

BWI is a measure of resistance of the material to grinding in a rod mill. The BWI of the petcoke depends on the type of crude being processed (generally, BWI is directly related to the metal content in the crude). Thereby, one of the major issues with the operation of the rod mill may be the dynamically changing BWI of the feed to the mill.
