Nonferrousmetal refining

 (MA-3000)
Roasting gases are used in the refining of non-ferrous metals including;copper, zinc, and lead.  These gases contain sulfurous acid gas, fromwhich sulfuric acid is produced.  Mercury is also abundant in the crudesulfide ore, and it is therefore necessary to remove the mercury in theprocess.  In addition to the removal of the mercury, it must be measuredand monitored in not only the gases, but the final products as well.
