Pollution from Mining

Pollution from Mining

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.

Flotation an overview ScienceDirect Topics

Flotation is a process of the physical-chemical separation of valuable species from gangue (waste material) that makes use of surface properties. The process is carried out in aerated tanks (cells or flotation columns) where the mineral particles are mixed with water and reagents that make the surface of the valuable mineral hydrophobic.
