aluminium geoscience australiaunlike metals such as copper, g, lead, iron and zinc which have been used by humans for thousands of s, aluminium has only been in common use for a little over 100 s. this is because aluminum is never found in its pure state in nature. so while humans knew about aluminium compounds, they only discovered how to extract aluminium metaliron and steel production in birmingham encyclopedia ofaug , 08· most of the woodward iron company's hings, for example, were linked by a remarkably short, mile railroad. the companyowned track extended outward from its blast furnaces and coke ovens, to its limestone and dolomite quarries, to its ore mines on red mountain and its coal mines along the edge of the warrior coal field.
underground hardrock mining underground hardrock mining refers to various underground mining techniques used to excavate "hard" minerals, usually those containing metals, such as ore containing g, silver, iron, copper, zinc, nickel, tin, and lead.it also involves the same techniques used to excavate ores of gems, such as diamonds and rubies. softrock mining refers to the excavation of softer minerals, such as saltiron ore reserves by country statistafeb , · iron ore are rocks and minerals that can be heated and used to extract metallic iron in an economically feasible method. both the iron and steel industries worldwide are reliant on iron ore
nonrenewable resource a nonrenewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. an example is carbonbased fossil fuels. the original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas. earth minerals and metal ores, fossil fuels (coal, petroleum, natural gasextraction of iron on a match head experiment rsc4.7a explain why the method used to extract a metal from its ore is related to its position in the reactivity series and the cost of the extraction process, illustrated by heating with carbon (including iron) edexcel combined science. topic 4 extracting metals and equilibria. obtaining and using metals
