The primary objective is to develop and/or improve methods for utilization of coal fly ash as a source of minerals. Processes are being studied for the recovery of aluminium, iron, and titanium from fly ash and for the utilization of residues. There are 4 tasks which include: development of the HiChlor process; improvement of the Lime-Soda Sinter Process; improvement of the Lime-Flyash Sinter Process; and the recovery and use of an iron-rich fly ash fraction. Progress accomplished during the quarter ending March 31, 1983, is reported. 6 references, 21 figures, 9 tables. (DMC)
