  • Chrome Sand Applications | African Pegmatite

    Unlike conventional sand moulds, chromite moulds can be hard to recover and reuse should there be moderatetohigh amounts of silica present This is due to a greater likelihood of the chrome becoming contaminated by the silica, and thus its refractoriness is reduced(3) Chrome sand refractories are typically used as a ‘facing sand’ in silica moulds(4) Green sand and other types of
