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].

Aluminium smelting Wikipedia

Aluminium smelting is the process of extracting aluminium from its oxide, followed by forming and baking at elevated temperatures. The quality of anode affects technological, economical and environmental aspects of aluminium production. Energy efficiency is related to the nature of anode materials, as well as the porosity of baked anodes
