The objective of this work is to examine methods for treatment of flue dust generated by brass smelting. Processes such as brass smelting generate metal which becomes flue dust. As a result of increasingly stringent government regulation of waste disposal it has become important to utilize flue dusts as sources of metals and other chemicals. For the production of industrial zinc oxide, low grade flue dust was mixed with coal and heated to the point where zinc vapour was formed. The vapour was burned immediately with air above the charge, and the finely divided zinc fume was carried with the exhaust gases and was collected in bag filter. The zinc oxide product was very finely divided. Because of its high purity (79.5 % Zn) it may be used as a pigment.
