Bavarder sur InternetAbstract. The properties of Smelter Grade Alumina, SGA, vary from refinery to refinery, and they also vary over time. Some physical properties, such as high fines content, have the potential to impact key smelting performance indicators more than others. These may affect production efficiency as well as environmental performance.
