EXTRACTION OF METALS - knockhardyorguk

EXTRACTION OF METALS Occurrence • ores of some metals are very common (iron, aluminium) • others occur only in limited quantities in selected areas • ores need to be purified before being reduced to the metal - this adds to the expense • high grade ores are therefore cheaper to process Theory The method used depends on the How Are Metals Extracted From Their Ores? | Reference,Metal extraction from ores occurs in many different ways involving physical, chemical and electrical means Even ores of the same metal sometimes require different methods of separation depending on the concentration of the metal and its chemical composition within the oreTypes of Extraction | S-cool, the revision website,Methods of extraction Many metals are found in the Earth's crust as ores An ore is usually a compound of the metal mixed with impurities When the metal is dug up, a method must be used to separate the metal from the rest of the ore This is called extracting the metal The method of extraction depends on how reactive the metal is
