Cast iron has already been mentioned above. This section deals with the types of iron and steel which are produced as a result of the steel-making process. Wrought iron: If all the carbon is removed from the iron to give high purity iron, it is known as wrought iron. Wrought iron is quite soft and easily worked and has little structural strength.

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.

There are several parts of mineral exploration that a geologist participates in. Those parts are mainly: * Describing known mineral deposits * Based on it's characteristics, determine where the ore "will be" as the mine digs deeper * Finding new...

The pentalenolactone biosynthetic gene clusters have been cloned and sequenced from two known producers of the sesquiterpenoid antibiotic pentalenolactone, Streptomyces exfoliatus UC5319 and Streptomyces arenae TÜ469.

The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the most-used metal by both tonnage and purpose.

The men of the search party formed the Jackson Mining Company on July 23, 1845, and iron mining in Michigan officially began. A furnace producing wrought iron from iron ore was erected on the Carp River, and it was there that the first metallic iron was made.

Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first separated from the gangue and then converted to pure iron.
