Roasters, smelting furnaces, and converters are sources of both particulate matterand SOx. Copper and iron oxides are the primary constituents of the particulate matter, but otheroxides, such as arsenic, antimony, cadmium, lead, mercury, and zinc, may also be present, along withmetallic sulfates and sulfuric acid mist. Fuel combustion products also contribute to the particulateemissions from multiple hearth roasters and reverberatory furnaces.
