Sludge is combined with a bulking material, such as other solid wastes or wood chips, and piled in windrows. Aeration is provided by periodic turning of the sludge mass or by mechanical aerators. The energy produced by the decomposition reaction can bring the waste temperature to 140-160°F, destroying pathogenic bacteria.

Flotation Concentration - Department of Chemistry

Waste rock particles do not adhere to the bubbles and drop to the bottom of the tank. The waste material that comes out of the bottom of the tanks at the tail end of this process is called "tailings." It is nothing more than ground-up rock with the copper minerals removed.

Environmental Impact of Flotation Processing

Environmental Impact of Flotation Processing . Valuable minerals in an ore can be separated from each other, and from worthless minerals, by the froth flotation process. The need for a process to extract ore arose from major sulfide mineralization after the oxide ores had been depleted.

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. 24/7 Online; EFD Home Page - Eriez Flotation Division - Canada

Introduction to Mineral Processing - cpchem.com

Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.

Induced gas flotation - Wikipedia

Induced gas flotation (IGF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by injecting gas bubbles into the water or wastewater in a flotation tank or basin.
