Pyrites analyzing 81% FeS2 and 19% gangue is burned in excess air to produce a
burner gas with an Orsat analysis of 5.84% SO2, 9.72% O2 and 84.44% Na. Analysis of
the cinder shows 8.29% unburned FeS2 and 3.81% SO3. The gases from the burner
are cooled and made to come into contact with Milk of Lime in an absorption
tower. The dolomitic lime used is 82% CaO, 16% MgO and 2% inerts. The bisulfite
liquor produced contains 7.05% total SO2 of which 1.15% is "free" and the rest 5.9%
being present as bisulfites. An analysis of the dry waste gas shows that it contains
only O2 and N2. Assuming no further oxidation of SO2 to SOs and formation of H,SO.
