    metals: extraction properties and uses- form 4 …

    Preliminary Steps Before Extraction Minerals (mineral) are usually mined with several impurities which lower the concentration of the metal per given mass or volume. Thus the ore is first concentrated before the actual extraction. Concentration is possible due to difference in properties between the mineral compound and the earthy materials

    Extraction of Metals. Industries extract metals from their ores. What are ores? Let me explain in a simple way. Usually, less reactive metals such as gold and silver are found in their pure form in the soil. But this is not the case with more reactive iron or aluminum. Usually iron and aluminum exist as compounds, with oxygen, also known as oxides
