Railroad Marbles - Ohio Metal Detecting

Often found near railroad beds are rough rusty-brown spheres of taconite or "iron" ore. These aren't really marbles, but I'll mention them here just to prevent any confusion. Taconite is a mineral containing about 25-30% iron in the form of magnetite. It was not a profitable source of iron until after World War II, and in the 1950s a process was devised that made it more commercially viable

Steel manufacture -

As with all large-scale manufacturing processes, the production or iron and steel generates by-products. On average the production of 1 tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of by-products. The main by-products produced during iron and crude steel production are slags (90%), dusts and sludges.

Iron - Essential Chemical Industry

Iron is produced by reduction of iron ore, which is often a mixture of oxides, using carbon, carbon monoxide, and hydrogen. While the blast furnace is the dominant reduction process other technologies are emerging which operate on a smaller scale. These are linked to locations where there is a plentiful supply of natural gas or low-grade coal.
