It is primarily composed of the insoluble fraction of the bauxite ore that remains after extraction of the aluminium-containing components. Iron oxides (10 – 30%), titanium dioxide (2 – 15%), silicon oxide (5 – 20%) and undissolved alumina (0 – 20%) make up the residue, together with a wide range of other oxides which will vary according to the initial bauxite source.
Mining equipment that's compact, cost-effective and durable over time has made a positive impact on mining efficiency and production. One of the greatest of these benefits is waste and chemicals reduction. The use of manganese dates back to the Stone Age when manganese dioxide created the pigments used in cave paintings.
