    OF A LOW GRADE ORE FROM VITI LEVU, FIJI By M. H. BUCKENHAM, Faculty of Technology, University of Otago. (Received for publication, 10 November 1%0) Summary Because of the increasing demand for manganese and the depletion of high-grade deposits considerable attention is now being directed at beneficiation of low-grade manganese ores.1. Iron ore - supply and demand outline 1.1 Types of iron ore Iron ores can be classified in different ways. The most important has to do with the iron content. In many cases, ore with a total iron content of 60% to 63%, or greater, is regarded as high grade, and ore with a lower iron content is regarded as low grade.
