Mining chemicals represent a niche area of supply but at the same time their use is almost universal across the industry. In this months im mining Spotlight Feature Article, from the June issue of International Mining magazine, Editor Paul Moore looks at the players, challenges, and future horizons for the sector.
Extraction of Iron and Steel Making Copper is extracted from its ores by chemical processes that involve heat or electricity and then electrolysis is usually used to purify the impure copper from the smelter.
The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace.
First, moistened concentrates are fed to a rotating drum or an inclined disc, the tumbling action of which produces soft, spherical agglomerates. These green balls are then dried and hardened by firing in air to a temperature in the range of 1,250° to 1,340° C . Finally, they are slowly cooled.
Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

Direct reduction, in which iron ores are reduced at temperatures below the metals melting point, had its origin in such experiments as the Wiberg Soderfors process introduced in Sweden in 1952 and the HyL process introduced in Mexico in 1957.
Iron ores in the form of hematite ferrous oxide and magnetite are removed from the earth through mining the use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore however because iron does not occur naturally it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
