Decomposition of ores by manganese dioxide: Analysis of chrome ore.
Pure manganese dioxide, prepared synthetically, has been used for the oxidative decomposition of chrome ores. The usual constituents of the ores, viz. Cr(2)O(3) FeO, Al(2)O(3), MgO, CaO and SiO(2) have been estimated and the results compare favourably with those obtained by standard methods.
