Mining activities are not new and indeed may have started in Neolithic (Chalcolithic) times to obtain the first metals for tool fabrication (Reardon 2011). In the Classic Greece and in the Roman Empire, many mines were exploited for production of iron, lead, copper, gold, and other metals.

From 1915 to 1965 the Iron Monarch and Iron BaronIron Prince mines were the main supply of ore for Australia's iron and steel industry. The favourable logistics of low cost of ore extraction and the nearby portsite at Whyalla, led BHP to establish an integrated steelworks at Whyalla in 1964.
Industry Background and Analysis Analyst: Michelle Ridsdale History Iron ore is used primarily in steel making. World crude steel production was 1,385mt in 2010, dominated by China, and has grown at an average rate of 5%pa since 2000. China's rapid steel production growth has reformed the world steel industry, shifting the centre of gravity from
emissions are mainly iron and calcium oxides. A cyclone cleaner, a dry or wet ESP, a wet scrubber or a bag house absorbs the sinter strand wind box emissions. The cyclone collectors are installed ahead of the induceddraft fans to remove particles with diameters of 25 μm or greater. The dry ESP opperates with removal efficiencies of up to
Progradex drill sampling products, services and consultancy will vastly reduce the potential for orebody failure, be it a new or existing operation, by identifying where the saleable ore is and providing grade data of such quality that definition can be improved to allow selective mining strategies adopted based on the commodity price of the d ay.

Dewatering tailings to higher degrees than paste produces a filtered wet (saturated) and dry (unsaturated) cake that can no longer be transported by pipeline due to its low moisture content. These filtered tailings are normally transported by conveyor or truck, deposited, spread and compacted to form an unsaturated tailings deposit (Davies and Rice 2001).

Although much smaller than the Mesabi iron range to the north, the Cuyuna was a major producer of iron ore for 80 years. More than 106 million tons of ore were mined and shipped from the Cuyuna range between its discovery, in 1904, and 1984, when mining ceased.
Vale has developed a revolutionary technique for processing iron ore in regions of high rainfall, which does not use water in the process. This technique avoids the need to build tailings dams, reducing impact on the environment. Called natural moisture or dry processing, it was put into practice, in 2008, on a trial basis at Carajás, Pará.
