Process Study of Fe,Ca and Mg Removal and Deep Impurity Removal with P204 from Low-concentration Cobalt Solution AITranslate
Abstract AITranslate
The pH condition of Fe, Ca and Mg removal from low-concentration coibalt solution and the process of impurity removal by P204 extraction were studied. The results form the preliminary iron removal experiment show that the process of iron removal with sodium jarosite and a pH value of 3.0-4.0 has a good effect of more than 99% iron removal rate. Using the process together with sodium jarosite and goethite,the iron removal rate is 95.65% and the cobalt loss rate is decreased from 21.3% to 4. 74%. The optimal pH value of the low-concentration cobalt solution to remove Ca and Mg for the above process is 3.5 4.0,and the optimal technical parameters of impurity removal by P204 extraction from orthogonal experiments are as follows, the volume fractions of P204 and petrol are 25% and 75%, respectively,the phase ra rio of oil to aqua is 1/2,and the saponification rate is 75%.
