| Abstract: | A new technology of roasting mixture of FeSO4, sulphur and pyrite to produce H2SO4 is proposed by utilizing 20 mass% H2SO4 and FeSO4 discharged in titanium dioxide production.Technological characteristics ,engineering difficulties and major equipment of roasting FeSO4 to manufacture sulphuric acid are described with emphasis. Successful operation of sulphuric acid plant based on FeSO4 solves the problems of waste and by-products to make the large-scale titanium dioxide plant achieved. |
