"Reprinted from Canadian Institute of Mining and Metallurgy Bulletin, Vol 49, 1956, pp. 274-280." "The electric smelting of five low-grade Canadian manganese ores has been investigated at the Mines Branch, Department of Mines and Technical Surveys, Ottawa. Ferromanganese, silicomanganese, and spiegeleisen were produced by special smelting processes from these ores since the latter were too low grade to be treated by conventional smelting methods. In one case the results were considered to be sufficiently promising to justify the construction of a pilot plant, by the Company concerned, for the further development of the process"--Abstract, p.
