    i have problem in the extraction of metals of highly ,The Extraction Of Metals

    Method of extraction depends on the position of the metal in the reactivity seri Metals at the top of the reactivity series (Potassium, sodium, calcium, Magnesium, Aluminium) which are very reactive and are highly stable and must be extracted by decomposing their compounds with electricity in an expensive process called electrolysis-05-20 The Extraction Of Metals , set and plates made of aluminium instead of silver Lower down on the reactivity series are most of the transition metals These are often found in.

    METALS AND NON-METALSppt

    The reaction between metal oxides and aluminium is highly exothermic and the metals are obtained in molten state Such reactions are called thermit reactions The reaction between iron oxide and aluminium produces molten ironExtraction of Low Reactivity Metals Metals like copper, mercury, silver and gold are less reactive Metals at the bottom of the reactivity series can be obtained by heating their compounds For example, when cinnabar (HgS) is heated in a furnace, it is reduced to metallic mercury Metals in.

    505 EXTRACTION OF METALS- METALLURGY

    The process of extracting pure metal from its ore is known as metallurgy Since, the nature of the ore and also the properties of different metals are different, therefore, it is not possible to have the universal scheme which may be applicable to all the metalsExtraction of Metals of middle reactivity: Iron, zinc, lead, etc are found in the form of carbonate or sulphide or Carbonate or sulphide ores of metals are first converted into respective oxides and then oxides are reduced to respective metals.

    Notes OCCURRENCE AND EXTRACTION OF METALSReactivity Series of Metals

    Metals having low reactivity show little affinity for air, moisture, carbon dioxide or other non-metals present in nature Such metals may remain in elemental or native (free) state in nature Such metals are called "noble metals" as they show the least chemical reactivity For example gold, silver, mercury and platinum occur in free state On the other hand, most of the metals are active and .Reactivity Series of Metals Some metals are chemically very reactive but some are less reactive The metals which lose the electrons readily, forming positive ions are more reactive than other metals which do not lose electrons readily.
