Includes bibliographical references. "CANMET initiated a project in 1975 - Alumina from Non-Bauxite Sources - the objectives of which were to evaluate potential domestic non-bauxite alumina sources, and to investigate and develop technology for the recovery of alumina from these sources. Potential sources are considered to be anorthosite, clay, nepheline syenite and coal associated materials which will be described in detail by others in a future report. The technologies for extracting alumina from raw materials can be classified as either alkaline sinter or acid processes. This report will review CANMET's laboratory work on acid extraction processes from anorthosite, clay and coal associated materials. Detailed descriptions of the experimental work can be found in the references to Division Laboratory reports made throughout the text"--Introd., p. 1. Includes abstract in French.
