Thermodynamic Analysis on Phosphate Decomposition of Scheelite AITranslate
Abstract AITranslate
Equilibrium diagrams of Ca-W-P-H_2O system are established on the basis of thermodynamic data.The diagrams,which are constructed under conditions of 25 ℃and 0.01 mol/L and 0.5 mol/L of total phosphorus-containing ions concentrations[P], show the effect of system pH value and total phosphorus-containing ions on system equilibrium.The results showed that phosphate solution is an efficient reagent for scheelite decomposition.High [P] is beneficial for the decomposition,but extras phosphate will cause difficulty in purification.In view of stringent requirement of ammonium paratunngstate as the intermediate product for impurity P,the author believe better decomposition can be obtained by proper improvement of pH value with low-concentration free P.
