Reaction Process and Mechanism of Scheelite Synthesis with Wolframite and Calcium Carbonate AITranslate
Abstract AITranslate
The reaction process and mechanism were studied of scheelite synthesis by calcination of wolf- ramite and calcium carbonate. The experimental results show that scheelite begins to form during wolframite calcination at 550 ℃. Wolframite and calcium carbonate can be completely synthesized into scheelite at 800 ℃, and the main products are CaWO4, Fe2O3 and Mn2 O3. Scheelite synthesis reaction in air takes place by two steps. The first step is generation of CaWO4, FeO and MnO, and the second step is oxidization of FeO and MnO into Fe2O3 and Mn2O3.
