More than 30 million cubic meters of water and tailings from iron ore mining were released into the environment. [6] Iron ore tailings dam breaks cause serious environmental damage and fatality in humans. Tailings impoundments also have the potential to seep. Seepage can be prevented or at least minimized by creating an impermeable layer. [13]
The Brumadinho dam disaster occurred on 25 January 2019 when a tailings dam at the Córrego do Feijão iron ore mine suffered a catastrophic failure. [1] The dam, located 9 kilometres (5.6 mi) east of Brumadinho in Minas Gerais, Brazil, is owned by the mining company Vale, which was also involved in the Mariana dam disaster of 2015. [2]
Mining oil shale impacts the environment it can damage the biological land and ecosystems. The thermal heating and combustion generate a lot of material and waste that includes carbon dioxide and greenhouse gas. Many environmentalists are against the production and usage of oil shale because it creates large amounts of greenhouse gasses.

The most commonly mined ore of copper, chalcopyrite, is itself a copper-iron-sulfide and occurs with a range of other sulfides. Thus, copper mines are often major culprits of acid mine drainage. At some mines, acidic drainage is detected within 2–5 years after mining begins, whereas at other mines, it is not detected for several decades.
