• Lead Ore Mineral Deposits in Nigeria with their Locations

    Among 44 countries that are into lead ore mining today just about five (5) countries account for up to 68 per cent of the total world s lead production. Lead is usually found along with other minerals such as zinc silver copper and gold (sometimes) during mining. This is so because large bulks of zinc deposit contain galena which is lead ore.
