Mineral processing is a form of extractive metallurgy that separates valuable minerals from the ore into a concentrated, marketable product. Mineral processing is also known as mineral dressing. Mineral processing is conducted at the site of the mine and is a highly mechanical process, with oversight from a central control room.

This disposal method is particularly reminiscent of modern and sealed embankments. This method requires much less space, is significantly safer and introduces the used process water directly back into the cycle. This method is clearly preferred, especially in hard-to-reach or constricted places with a high risk of earthquakes.
