For mining purposes, big machines are often used in order to make the mining process more effective and to reduce the physical work for miners. However, these machines emit large amounts of harmful gases, also including greenhouse gases like methane or CO2. Thus, mining can also cause air pollution and the implied consequences.

Bauxite tailings are produced during the Bayer Process which is the most commonly used method of refining bauxite to aluminum oxide. Estimates indicated that roughly 95% of the aluminum oxide produced in the world was made through the Bayer Process. After the bauxite ore is extracted from mines, it is taken to a plant where it is refined.
