History of Metals Timeline (Text Version) There are currently 86 known metals but before the 19th century only 24 had been discovered and, of these 24 metals, 12 were discovered in the 18th century The Metals of Antiquity, were the metals upon which civilisation was based
An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit The ores are extracted from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements The grade or concentration of an ore mineral, or metal, as well .
The extraction of aluminum from its ore and subsequent processing into finished prod- ucts takes place in a series of successive operations, each largely independent of the other Generally the various processes are carried out at different plant sit

Aluminum Ores ores from which the metal aluminum is obtained There are a large number of minerals and rocks containing aluminum; however, only a few of them can be used for extracting metallic aluminum Bauxites are the most widely used raw materials for aluminum Initially a semifinished product, alumina (A12O3) is extracted from the ores, and the .
Nickel is a strong, lustrous, silvery-white metal that is a staple of our daily lives and can be found in everything from the batteries that power our television remotes to the stainless steel that is used to make our kitchen sinks
In the industrial process for making copper metal from chalcopyrite ores, copper concentrate being about 5-10% copper with the rest being sulphides, iron and other minerals is reacted in a high intensity smelter with oxygen
the extraction of metals - an introduction This page looks at the various factors which influence the choice of method for extracting metals from their ores, including reduction by carbon, reduction by a reactive metal (like sodium or magnesium), and by electrolysis
chief ores of aluminum Aluminium does not occur in free state, but it is widely distributed in nature in the form of compounds The chief minerals of aluminum are either silicates or oxid
Introduction Aluminium is too high in the electrochemical series (reactivity series) to extract it from its ore using carbon reduction , Aluminium ore The usual aluminium ore is bauxite Bauxite is essentially an impure aluminium oxide The major impurities include iron ,
