The macroscopic morphology of the chrome ore is shown in Fig. 1. The block size of the lump ore ranges in 10–50 mm. The texture is very compact, the speci fic gravity is 4.6, the surface is grayish black, mingling with some sporadic light white, yellow and green materials. There are no speci fic cleavages appear after breaking the ore.

Chromium and copper were analysed in 2007 samples (mine M4) because these elements might be associated with platinum emissions. Platinum is mined from chromium-rich minerals (Cawthorn 1999), and elevated Cu concentrations have been reported in soil from a tailing disposal facility at a South African Pt mine (Maboeta et al. …
