Manganese Mn is a brittle hard grey white metal that looks much like iron and is an essential additive to steel But most manganese used as an alloying element in steel In ore production about 30% of the manganese used to refine ore and about 70% used as an alloy in the final product Manganese is not on the radar of many investors

·Cave artists in France used the black ore manganese dioxide or pyrolusite at least 30 000 years ago Pliny the Elder a Roman philosopher wrote in the first century that it was also used
Bulk Manganese Ore Manganese Ore is used as an alloy of iron ferro manganese and is essential to steel making and for certain other industrial processes acting as a toughener and a cleanser removing sulphides and Manganese Ore is widely available and exported in dust or in lumps in some quantity from West and South Africa India and Australia
·It is a world class chemical sedimentary deposit with an annual production of Mt equivalent to 10% of world supply Most of the ore is exported with some shipped to Bell Bay in Tasmania for the production of manganese alloys 200 000 t/year World resources of manganese ore are large but irregularly distributed and of low grade
