Key words: ore losses, ore recovery, mining method INTRODUCTION At the present time the undergound exploitation of bauxite is primary for ore deposits of high quality, resulting that the high quality ore was mixed with ore of lower quality from the open pits, which
Aluminium is the third most abundant element in the Earth's crust, but does not occur as a metal naturally. The first step in producing aluminium is mining its ore – occurs mainly in tropical and subtropical areas, like Africa, the West Indies, South America and Australia – there are some small deposits located in Europe.
growth in the metals and mining sector. Demand for iron and steel is set to continue, given the strong growth expectations for the residential and commercial building industry. There is significant scope for new mining capacities in iron ore, bauxite and coal. Considerable opportunities for future discoveries of subsurface deposits.
