Extraction of Metals. - GCSE Science - Marked by Teachers.com

The least reactive metals are found native as elements e.g. silver, gold, but most are found in compounds, usually oxides or sulphides. The occurrence in nature of metals will affect the cost of extracting and engineering them. Most metals are found as ores usually either as an oxide or a sulphide.

Metals are generally extracted by the following steps: Ore concentration: an ore is never completely pure compound and is found with several other impurities which need to be removed hence increasing the availability of metal for the extraction process. Extracting the required metal using a suitable process: After choosing a suitable process based on the reactivity of the required metal several precautions need to be taken since many ores do not contain just one metal hence a suitable ...

An ore is any naturally-occurring source of a metal that you can economically extract the metal from. Aluminum, for example, is the most common metal in the Earth's crust, occurring in all sorts of minerals. However, it isn't economically worthwhile to extract it from most of these minerals. Instead, the usual ore of aluminum is bauxite - which contains from 50 - 70% of aluminum oxide.
