Improvement of a continuous process for the production of tungstic trioxide from scheelite : preleaching the scheelite with weak hydrochloric acid / J.A. Vezina and W.A. Gow, Extraction Metallurgy Division. : M34-20/104E-PDF

“The effect of leaching Canadian scheelite concentrates with weak hydrochloric acid at pH 1.0 prior to treatment by a previously described Mines Branch process was investigated. The work showed that the weak-acid leach removed about 25 per cent of the iron, 90 per cent of the phosphorus, 10 per cent of the calcium and 0.1 per cent of the tungsten from a scheelite concentrate analysing 54.4 per cent WO3 , 15.8 per cent CaO, 3.9 per cent Fe, and 0.43 per cent P. The overall cost on the basis of acid consumption and tungsten loss would be about $0.04 less per pound of tungsten than for the original Mines Branch process where the weak-acid leach was not used"--Abstract, p. i.
