Evaluation of Technology for the Recovery of Metallurgical-grade Alumina from Coal Ash.
NTIS: PB 299 567 :9 pages
The Bureau of Mines has reviewed the literature related to the recovery of al2o3 (alumina) from coal ash. A small amount of unpublished data is also reported. Of the processes studied, the alkaline-sinter process is the most promising from a technical standpoint. However, owing to the high cost of processing coal ash, the dispersed location of powerplants, and the domestic availability of higher grade alternate materials, coal ash does not rank as a primary source material for replacing imported bauxite.
