Mineral Processing and Extractive Metallurgy Review

MgO enrichment in ferrochrome slag can be achieved by a method comprises of grinding of granulated ferrochrome slag in presence of magnesite raw material followed by compaction and sintering. The ratio of MgO/SiO 2 > 2.2 and MgO/(Al 2 O 3 + Cr 2 O 3) > 1.71 in the final composition ensures the refractoriness above 1665°C.
