Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone CaCO 3 and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.
The upper sequence contains the manganese deposits. The manganese ore is a sedimentary layer, consisting of manganese strata occurring between clay and sand beds. The ore body is essentially stratabound and strataform in character and it represents a continuous horizon up to 11 m thick. The ore body consists of pisolitic and oolitic manganese ...

Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds andor saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
