    The review will not address alumina production from non-bauxitic materials such as clays, shales, nephelines or fly ash. It will also not consider alumina production by non-alkaline processes such as those using mineral acids or reduction. For a comprehensive review of these processes (up until ∼ mid 1980's) see O'Connor (1988).
