mills for taconite

Taconite Mining and Processing Industry Profile - epa.gov

The taconite ore slurry discharged from the rod/ball mills is passed through multiple stages of magnetic separation (EPA, 2001). In some cases, autogenous grinding can be used to replace the cone crushers and rod mills. Autogenous mills use coarse pieces of the ore itself as grinding media instead of steel balls and rods (Kirk-Othmer, 1995).
