Environmental Impacts of Lead Ore Mining and

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 the total volume of the mined material. In the metal industry, production of lead, causes the greatest degradation of the environment.
