Loading chromite ore underground
Geology and Operation:
The underground mine is operated by Glencore Xstrata and the chromite ore is mainly from the LG-6 chromitite layer of the Bushveld Complex. Two chromitite layers are processed in the smelter facility which consists of 4 semi-enclosed electric arc furnaces fed by two pelletising plants.
The chromitite layers occur in the lower part of the critical zone of the Bushveld Complex and the layers are up to 1m thick. The mineralogy is relatively constant consisting of predominant chromite, with minor plagioclase and orthopyroxene.
The friable ore chromite is beneficiated, and mixed with a binder to produce pellets and fired in grate furnaces. The pelletised ore is then smelted in submerged arc furnaces to produce a ferrochrome product
and a slag which is discarded.
The trip will involve a visit to the mine and smelter facility.
