A lead sintering machine processing 100 tons/day of sinter at 6% S content removes 80% of the S in the ore as SO. (Figure 13-4). The exhaust gases from the machine are proc essed through a single-stage sulfuric acid absorption plant, where 96% of the SO, is con- verted to concentrated sulfuric acid (H2SO4).
