Mining is the extraction of valuable minerals or other geological materials from the earth. Mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.
Steel is produced in an energy intensive process by reducing iron ore, or by melting recycled scrap. Hundreds varieties of steel products are used in a very wide range of applications by industries like mechanical, shipbuilding, automotive, appliances and packaging, construction and transport. Steel is recovered from end of life goods and recycled without loss of its intrinsic properties, which adds to its competitiveness and environmental benefits.
