A system for beneficiating landfilled or ponded waste coal fly ash makes use of a carbon reduction kiln comprising multiple independent heat zones so that the waste coal fly ash is preferably exposed to indirect heat when received in such zones. The system may include a carbon capture system operatively connected to the carbon reduction kiln.

Ponded ash beneficiation system and related methods

A ponded ash beneficiation system and related methods treat either landfilled or ponded waste coal fly ash by removing at least 75% of the carbon from a collected quantity of such waste coal fly ash. Analysis and testing of the collected waste coal fly ash to determine optimal air balance, indirect heat temperature and retention time. Subjecting a stream of such waste coal fly ash to temperatures ranging from 900° F. and 1150° F. along with air addition calibrated as a function of the LOI of the carbon in such waste coal fly ash. This stream is exposed to the foregoing range of temperatures and corresponding air addition for a range of time between 20 minutes and 90 minutes, in certain aspects of the disclosure.
