The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal is a key part of the cokemaking process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are ...
· Less common ores are braunite containing about 70% manganese, manganite (Mn2O3. H2O) with 62%, and rhodochrosite (MnCO3) with 48%. Rhodonite, (MnSiO3), is sometimes found mixed with other manganese ores. Bog manganese (also called wad) is of variable composition. It is like bog iron, but is darker, often quite black.
