The produced alloys contain 5075% Cr depending on ore composition, around 12 % Si and about 89%C typically. South Africa HCFeCr has a lower Cr content of 5053 % compared to that produced in other parts of the world which have a 60+ % Cr content. This is due to the lower Cr:Fe ratio found in South African chromite ore.

Market summary Chromite, or iron chromium oxide (FeCr2O4), is the mineral source of chromium. In its purest form, chromite comprises chromium (Cr2O3) at 68% and iron oxide (FeO) at 32%. Highpurity chromite deposits are rare, due to the natural replacement of chromium and ferrous iron by other elements.

The ball mill treatment reduced chromite grains greater than µm down to sizes less than µm in diameter, and thus released chromitebound Cr(VI) for sulfide reduction. Magnesioferrite encapsulated Cr(VI) was released and reduced similarly with grain size change from to µm to below µm.
The experimental results show that the mill scale in the alloying mixture is reduced to high active iron first and disseminated around the chromite ore particles; the reduction of chromite ore is enhanced with the addition of mill scale especially at temperatures higher than 1623 K, and the enhancing effect increased with increasing mill scale ...
