Recovery of metal oxides from fly ash. Volume 1. Executive summary - financial evaluation. Final report
An engineering, cost and financial evaluation study was carried out for a conceptual commercial plant to process fly ash into marketable metal oxides by the direct HCl acid leach process. The proposed plant site was adjacent to the TVA Kingston, Tennessee power plant and was sized to process 1 million tons of ash (dry basis) per year. The capital cost requirements for the HCl direct acid leach (DAL) optimized process plant were estimated to be $244,390,000. Based upon the reported Kingston plant fly ash analysis and extractability, the conceptual commercial plant would annually produce about 158,000 TPY of alumina, 102,000 TPY of ferric oxide, 46,000 TPY of gypsum, 81,000 TPY of alkali sulfate salts, 866,000 TPY of spent fly ash and 1,940,000 kWh of excess cogeneration power. Potential long term average revenues were projected to be $126,400,000 per year which would indicate a commercial project's economics may be quite adequate. Volume 1 of this study report presents the investment and operating cost data, revenue considerations and an evaluation of profitability. Volume 2 presents the engineering data and capital cost estimates and Volume 3 presents the commercial facility design criteria. 16 references, 16 figures, 20 tables.
