Abstrakt: The feasibility of preparing iron(III) molybdate + molybdenum trioxide precipitates with the lowest possible iron oxide content has been studied theoretically and experimentally. The precipitates obtained were characterized by IR spectroscopy, thermal analysis, X-ray diffraction, and X-ray fluorescence analysis. The results demonstrate that precipitation through continuous crystallization at a constant acidity of the mother liquor (pH ≤ 1) allows one to obtain precipitates containing down to 2% FeO.
