Zinc - Simple English Wikipedia, the free encyclopedia

Then the zinc sulfide is heated in air to make zinc oxide and sulfur dioxide. 2 ZnS + 3 O 2 → 2 ZnO + 2 SO 2. The sulfur dioxide is oxidized to sulfur trioxide. 2 SO 2 + O 2 → 2 SO 3. The sulfur trioxide reacts with the zinc oxide to make zinc sulfate. This makes a soluble form of zinc which can be processed more.
