Iron Ore Mining Essentials: Key to Steel Production

The first step in the process is the production of pig iron from which the iron ore is converted in the blast furnace and usually occurs in the form of iron oxides. The heated air is blown into the furnace at the bottom which assist in the coking to be burnt and to produce high temperatures (about 1,500°C).

Ore | Processing, Extraction & Refining | Britannica

Special bacteria are sometimes used as part of this process. After recovery, the metals may be still further refined (purified) or alloyed with other metals, as in a copper refinery or steel mill. Mining, processing, and refining are thus successive steps in the utilization of an ore deposit to yield a metal. William Andrew Hustrulid
