DURAMET® is a magnetic ferro silicon produced in electric arc furnaces and subsequently milled to size ranges required. In addition, DURAMET® contains aluminum and titanium which enhances its resistance to corrosion.


DURAMET® is used in slurry density applications for heavy media separation and sink-float processes. DURAMET® is an accepted medium for the gravity separation of minerals, aggregates and metals with a specific gravity of approximately 2.0 to 4.0.
