Refractory ore beneficiation - ALLAN; BENJAMIN W.

Another sample of the preroasted reduced Australian ore of Example IV was similarly electrolyzed but a 10 weight percent solution of sodium sulfate was used in the cell in place of the ammonium chloride. Unlike the results in the prior experiment, the cell liquor became alkaline (pH 11.0), and the iron and other hydrate-forming metal oxides precipitated in the cell liquor. Nevertheless, the ...
