Mar 01, 2009 Generally, silver comes to market as a byproduct of the industrial mining of other metals, such as copper, zinc and gold. In 2005, only 30 per cent of silver came from actual silver mines. It is no high honour to be grouped into one of the worlds most destructive industries, as the industrial mining industry is known.
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.
