 · Mining provides essential raw materials for an industrialized society. However, it causes serious pollution of surface and groundwater. Transferring minerals from deep below the surface to the surface promotes oxidation reactions. Oxidation of iron salts and of sulfur-containing materials in the presence of water leads to highly acidic solutions.

Water is essential to mineral processing. It is used in various steps in the process to recover valuable metals from ore. The water use is quite high – for example, around 1600 litres of water are used to obtain the 19 kilograms of copper found in a medium-sized family car. Water is not always readily available for processing operations.
