Hands on advice for successful sand reclamation Castings SA

Fortunately, since chromite is the smaller portion of the usual system, the opposite situation (i.e. with low concentrations of fine particle silica) is unlikely to cause the silica-chromite burn-in. Elemental Iron (Fe) accounts for about 20% by weight of the chemical composition of foundry-type chromite sand.
