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].
