Slag - Wikipedia
Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of ...Get Price
Newark Processing - Ohio EPA
Newark Processing received two types of dross: white dross, which contained a high enough aluminum content to be fed directly into a rotary furnace for smelting, and black dross, which needed to be processed through a wet mill to concentrate aluminum before smelting. Both the furnaces and wet mill generated by-products (saltcake and dross fines, respectively) that were stockpiled on-site. The ...Get Price
