Production of alumina from Ouse bauxite by the Bayer process.

Considerable bauxite deposits were discovered in Tasmania towards the end of 1941. The purpose of this investigation was to carry out analyses of representative samples from the Ouse and Swansea deposits and to discover to what extent the Bayer Process was suitable for the extraction of alumina from the Ouse bauxite. This thesis embodies details of the above two aspects together with outlines of the methods of analyses enployed. Preliminary work on the dry extraction process using sodium carbonate is also included. Analyses of four samples of clay. occurring in the immediate vicinity of the Ouse deposits are listed in the Appendix
