· Integrated mills produce steel using raw materials such as iron ore, coke – produced from coal – and limestone. To produce coke, coal is crushed, ground into a powder and heated in an oven. After the coke is cooled, it is reduced, or smelted with iron ore and limestone in a blast furnace, or basic oxygen furnace. The molten iron is then either cast into pig iron or moves to the next stage ...
Iron ore can be extracted underground by using tunnelling and shaft equipment, or it can be sourced at ground level through the use of open pit mines (also known as surface mines). Iron ore is then transported and shipped to milling plants. This guide provides information on Standards, Certifiion schemes and other industry specific information that may be of interest to anyone working ...

For every ton of steel recycled, 2,500 pounds of iron ore, 1,400 pounds of coal, and 120 pounds of limestone are conserved. Recycling steel saves nearly 74% of the energy used to produce it from raw materials — that's enough energy to power about 18 million homes for a full year. How to recycle it. Look for curbside recycling bins, local recycling dropoffs, or scrap buyback centers. What ...
