It is important to evaluate the environmental impact of steel manufacturing. Several countries have imposed environmental safety regulations to restrict the amount of GHGs (especially Co2) emitted by the industrial sectors. This places pressure on steel manufactures to come up with new processes or techniques to produce high-quality steel while reducing Co2 emissions and limiting energy ...

In order to return to lower energy states, iron and steel frequently combine with oxygen and water, both of which are present in most natu-ral environments, to form hydrated iron oxides (rust), similar in chemi-cal composition to the original iron ...

Tailings are a type of rock waste from the mining industry. When a mineral product is mined, the valuable portion is usually embedded in a rock matrix called ore. Once the ore has been stripped of its valuable minerals, sometimes through the addition of chemicals, it is piled up into tailings. Tailings can reach immense proportions, appearing in the form of large hills (or sometimes ponds) on ...
