  • Environmental Impacts of Lead Ore Mining and Smelting

    Present day lead pollution is an environmental hazard of global proportions. A correct determination of natural lead levels is very important in order to evaluate anthropogenic lead contributions. In this paper the impact of mining and smelting of lead metal ores on environmental quality is described. Globally mines produce large amounts of waste because the ore is only a small fraction of
