Lithium minerals, lithium and its compounds have assumed great military and civilian significance after the Second World War.The name comes from the Greek word lithos. Lithos translates to 'stone'. It was given this name because it was first discovered from a mineral rather than a plant.ut of the lithium minerals, lepodilite has wide-spread occurrence, but it is less favoured by industries than spodumene and amblygonite because of the lower percentage of lithia. Sondumene has become the chief commercial source of lithium because of its regular supply and comparatively high Li 2 O content.
