Staurolite is a general-purpose mined mineral abrasive used to remove thin coatings, rust, and mill scale. Its sub-angular shape is ideal for applications where a minimal surface profile is required. Staurolite is excellent for achieving a near white finish and is commonly used for new steel applications; including storage tank & tower construction, structural & plate steel blasting, and steel fabrication.
