    mining Underground mining Britannica

    The openings made in the process of extracting ore are called stopes or rooms. There are two steps involved in stoping. The first is development—that is, preparing the ore blocks for mining—and the second is production, or stoping, itself. Ore development is generally much more expensive on a per-ton basis than stoping, so that every effort ... read more

The product consists of approximately 90% reduced iron. read more

  • PRODUCT GUIDE ICE

    PRODUCT GUIDE ICE

    A simple way to look at iron ore is that it starts as fines (heavy grains, like sand), is turned into pig iron, which in combination with coking (metallurgical) coal, and energy can then produce crude (liquid) steel, which is finished (rolled) into either in long (e.g. Rebar) or flat (Hot Rolled Coil) form. read more
