Recycling one tonne of steel saves 1100 kg of iron ore, 630 kg of coal and 55 kg of limestone. Recycling one tonne of steel saves 642 kWh of energy, 1.8 barrels (287 litres) of oil and 2.3 cubic metres of landfill space. Every tonne of steel made from recycled scrap saves enough energy to power four homes for a whole year.This rock-like or earthy substance is called iron ore. • Iron Ore represents – according to the mining sector – an iron content of between 30 to 70 percent of total weight. It exists in various combinations, e.g. in the relationship of 2 atoms iron (2 x Fe) and 3 atoms of oxygen (3 x O2), Fe2O3 = iron oxide. • Hot metal is the ...
