short note on the extraction of metals
EXTRACTION OF METALS
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 . . ....
