Flotation Froth - an overview ScienceDirect Topics

For example, froth flotation is a technique commonly used in the mining industry. In this technique, particles of interest are physically separated from a liquid phase as a result of differences in the ability of air bubbles to selectively adhere to the surface of the particles, based upon their hydrophobicity.

Froth Treatment Explained Oil Sands Magazine

Mar 08, 2016  In an oil sands mining facility, the froth produced in Extraction is only 50 to 60% bitumen with a relatively high concentration of fine solids (up to 15%) and can contain as much as 40% water. This bitumen froth is further processed in Froth Treatment where water and solids are removed using a solvent or light hydrocarbon.

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.
