Beneficiation Tests on Andalusite Ore from the Marico District

摘要

Samples representing 10 boreholes and the face of an open-pit quarry were evaluated for their contents of recoverable andalusite and the quality of the andalusite contained by the use of a standard evaluation procedure developed at the Council for Mineral Technology. The evaluation of the borehole samples showed that the yield of andalusite would be low, the average yield being less than 6,0 per cent for the Kleinfontein area. The quality of the andalusite, except for one borehole, was generally below that required by the present market, particularly in terms of the high Fe2O3 content. A procedure is recommended for the treatment of the ore.
