Steel is made by the Bessemer, Siemens Open Hearth, basic oxygen furnace, electric arc, electric highfrequency and crucible processes. In both the Acid Bessemer and Basic Bessemer (or Thomas) processes molten pig iron is refined by blowing air through it in an eggshaped vessel, known as a converter, of 1525 tonnes capacity.

The HIsarna steelmaking process is a process of primary steelmaking in which iron ore is processed almost directly into steel. The process is based on a new type of blast furnace called a Cyclone Converter Furnace, which makes it possible to skip the process of manufacturing pig iron pellets, a necessary step in the basic oxygen steelmaking process.

Room and pillar mining often leads to retreat mining, in which supporting pillars are removed as miners retreat, allowing the room to cave in, thereby loosening more ore. Additional subsurface mining methods include hard rock mining, which is mining of hard rock (igneous, metamorphic or sedimentary) materials, bore hole mining, drift and fill mining, long hole slope mining, sub level caving, and block .
