Environmental Impacts of Metal Ore Mining and

1997-5-1  The impact of mining and smelting of metal ores on environmental quality is described. 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 Cu, Pb, and Zn causes the greatest degradation of the environment.

Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore.Iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times. Prehistoric people first mined flint, which was ideal for tools and weapons since it breaks into shards with sharp edges.
