ABSTRACT

Power plants from Oltenia’s region represent a major source of industrial wastes. Ash is the most important waste produced by power plants from coal combustion. The physical-chemical properties of ash vary substantially between producers and depend on the quality and the composition of fossil fuels that are used in modern power plants, as well as on combustion conditions. The diverse chemical, mineralogical and morphological properties of ash offer an opportunity to process it and recover various fractions with particular attributes. The main constituents are Al2O3, Fe2O3, CaO, MgO and in smaller quantities Na2O and K2O. Also, ash resulting from burning lignite from Oltenia Mining Basin has an important content of heavy and rare metals, carbonaceous solid residue, which may be recovered properly through extraction technologies.

KEYWORDS
