Research on Recovery of Synthetic Rutile Leaching Liquor

Ruthner acid regeneration device is used to recovery of synthetic rutile mother liquor.Based on a comparative analysis on steel sheet pickling solution and synthetic rutile mother liquor in respects of chemical composition,concentration,density and viscosity,parameters such as hearth temperature,air-coal ratio,spray flow,absorption flow have been optimized The effects of these parameters on Cl^- decomposition rate have been investigated,So the optimal process parameters are ascertained accordingly.Reclaimed acid with a concentration of 218.6 g/L and ferric oxide with TFe≥65% were abtained.Then,an effective solution to comprehensive recovery of synthetic rutile mother liquor has been offered.
