The results of two-stage roasting of pyrite concentrate with air blowing and the principle scheme of the process are presented in the report. The results of experimental sulfuric acid production tests using pyrite concentrate to generate sulfurous rich gas containing 0.1 – 0.15% of sulphur trioxide are shown. Comparative characteristics with technologies known for the present are given.
