Coal Agloflotation: A Remediation Technique for Cleaning of Town Gas Soils
The use of a "clean" fuel and the treatment of contaminated soils are two factors that can greatly improve the environment. Coal, which occurs in great abundance in the USA, is widely used both in the small-scale domestic and in the large-scale industrial market. Apart from high sulfur content, a high ash content of coal is undesirable. Soils contaminated with polycyclic aromatic hydrocarbons (PAHs) are a potential threat to health and the environment and need to be treated. The present study investigates the use of a hydrophobic coal surface for the adsorption and removal of oily/tarry contaminants such as PAHs from town gas soils. The agloflotation process uses a coal-soil-water mixture to achieve simultaneous removal of mineral matter from coal. The cobeneficiation achieves 90% and higher decontamination for soil and 40% and higher ash removal from coal.
