Environmental Impacts of Metal Ore Mining and …
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.

The Disadvantages of Smelter | Sciencing
The process of smelting is when industrial factories extract or smelter purer and more refined metals from ores. Metals like copper or lead are often extracted using this process from earth samples and deposits. Although smelting helps with metal productions, there are many disadvantages to smelting that impact the environment.

Impacts of Smelting - Base Metal Smelting
Smelting is known to be a major cause of pollution in the environment. When smelting occurs, along with the metal produced, a solid waste product, called stag, is also produced [1]. This slag is emitted into the air and can be a cause of the pollution although not a major one. The majority of the pollution is caused by air emissions [1].
