Abstract

Abstract

The reduction leaching conditions for pyrite cinder leaching by titanium dioxide waste acid were investigated and optimized, using the response surface methodology designed by Box-Behnken method, and the iron powder dosage, reduction time, and leaching temperature were selected as the three variables. The established predictive model for leaching conditions was with good fitting results to predict leaching yields or optimize leaching variable values. The regression equation model was significantly reliable, with a correlation coefficient R² of 0.9961. The leaching conditions had important effects on the leaching reaction equilibrium, solubility of leached materials, and properties of reaction systems, among which the synergistic interaction between iron powder dosage and leaching temperature had the greatest impact. The verification experiments confirmed that the leaching yield values could be achieved over 83.63% under the optimal conditions, with the iron powder dosage of 10.347 g, reduction time of 2 h and leaching temperature of 88 ℃.
