- W2010167103 abstract "The reaction kinetics for the leaching of scheelite CaWO4 by hydrochloric acid in the presence of a complexing agent, phosphate ion, have been studied in a stirred reactor to determine the effect of the important process variables, such as particle size, temperature, stirring speed, acid concentration and phosphate addition. In the presence of sufficient PO43− corresponding to P:W ⩾ 1:10, only soluble 12-tungstatophosphoric acid H3PW12O40 instead of insoluble tungstic acid H2WO4 is formed, and the rate of leaching is greatly accelerated without fine grinding of the ore. The conclusion, that the reaction at the solid-liquid interface governs the major portion of the leaching process, is supported by an apparent activation energy of 18.9 kcal/mol (79 kJ/mol) and by the insignificant influence of increasing the stirring speed from 800 to 1000 min−1. The shrinking core model is considered to describe the whole process and an empirical rate equation was found to be k̄ = k̄0CHCl1.47CPO40.31S0.53 e−(18,900RT) (eqns. 15 and 16)." @default.
