Described and claimed herein is a method of producing enhanced combustion ash for use in pozzolanic applications or cement clinker manufacture. The method employs a primary process in which wet or dry feedstock is pulverized with sonication using one or more grinding media having a maximum component size of about 2 mm. Alternatively, the media may have a true grinding medium volume to chamber volume ratio of at least 0.29. Also disclosed an claimed is an enhanced combustion ash produced by the method, whereby the enhanced combustion ash has one or more qualities that make it particularly suitable in pozzolanic applications or cement clinker manufacture.

Upgraded combustion ash and its method of production

The invention consists of a method for treating polychlorinated biphenyl (PCB) contaminated media by: a) combining the media with a fluid containing one or more liquid hydrocarbons to form a media/fluid mixture; b) sonicating the mixture at audio frequency to extract PCB from the media into the fluid; and c) treating the fluid with sodium-containing alkali metal. The method may include additional steps to reduce the size of the media. Alternatively, the fluid can be decanted from the media after sonication and treated separately with sodium-containing alkali metal.
