Titanium dioxide was prepared,using the sulfuric acid by the sintering gas desulfurization in Pangang as the raw material of acidolysis process.The tendency and distribution of harmful elements in the acid during the titanium dioxide production were tracked and monitored,and the meta-titanic acid satisfying the requirements was eventually obtained.The feasibility of applying sulfuric acid by sintering gas desulfurization to the titanium dioxide production was verified.The results indicate that the equal level of acidolysis rate for titanium concentrate is reached by the sintering gas sulfuric acid in comparison to the sulfuric acid in laboratory.However,sulfuric acid by sintering gas desulfurization cannot be used in the processes of washing and coating in titanium dioxide production due to the black color of the acid.The waste acid and water,produced in the production of titanium dioxide by the sintering gas sulfuric acid,do not harm the environment.
