The plant can process 1000 tpd of the ore and the metal has the following composition: The desulphurization unit plays an important role in this process and removes SO; gas. Calculate the concentration of SO2 gas emitted from the sulphurising unit if stream 3 has a mass flow rate of 3kgmin1 and a concentration of 2mol3dm3. - List all assumptions clearly. - Show all working. - Ensure that your logic is clearly explained
