The study is for highly efficient recovery and utilization of TiO2 in SCR catalyst wastes,it takes SCR catalyst leaching titanium slag after sodium salt roasting as raw material and takes concentrated sulfuric acid leaching for a hydrolysis reaction.The study was carried out by using system experiments to investigate the effect of sulfuric acid concentration,liquid-solid ratio,titanium slag particle size,reaction temperature and reaction time on acid dissolution rate of titanium slag.It successfully realized the highly efficient acid dissolution of titanium slag under the best experiment parameters that the maximum acid dissolution rate can reach 93.7％.
