Until recently, mining operations were thought to have only a small comparative impact upon the rainforest, which covers 40% of South America. Estimates previously put the figure at just 1%-2%; however, a new study published by researchers at the University of Vermont (UVM) is as much as ten times that.

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.
