description of the processes involved in extracting iron from the iron ore
The Mining of Iron Ore. Iron ore mining was a thriving industry in many parts of the world, with the smelters being located as close to the mines as possible. However as larger mines where more efficient mining of higher iron content ore became effective, the smaller mines fell by the wayside.
mining iron ore costs are omitted – energy/machinery involved in digging out the ore, crushing it, transporting the ore, and the cost of actually extracting the iron from its finite ore resource – chemicals needed (coke, limestone), constructing and running a blast furnace
