UG2 Chromite White Paper (October 2015) This seam is characterised by high levels of low grade chrome ore (UG2). Traditionally, platinum producers would stockpile this resource as waste material. However rising platinum mining costs and increased smelting capacity in China, enabled UG2 chrome to be sold as a byproduct.

Refractories. Chromite is an important refractory material, although production for this purpose is only approximately 1% of world production of chromite. Refractory grade chromite requires a very low silica content, typically % SiO2. The chromite is generally produced as a finegrained concentrate from which most of the silica, which .
Electron microprobe and petrographic analysis of accessory chromite shows that it is fine grained (average grain size mm), generally lower in Cr2O3, and has a lower Cr/Fe ratio than segregated chromite. In addition, unusual patchy zoning is exhibited by some accessory chromite.
