Gangue minerals, once separated by mineral dressing processes of (most of) the valuable ore minerals and dumped in mine tailings may be a significant environmental impact. In particular, oxidation of pyrite, a common gangue mineral, is one of the main sources of acid mine drainage. Reuse. Minerals that were once thought of as gangue, and were dumped, may later find a commercial use.

Products impact the environment at several stages. Energy and waste are created when raw materials to make the product are extracted and transported and when these materials are changed to create manufacturing materials. For example, iron ore must be converted to steel, and product parts must be created from steel.
