    In most instances, both phases are molten such as the matte and slag in a conventional copper smelting operation. The gas phase may also be used to advantage, either as a means of separating valuable volatile constituents or for removing unwanted volatile impurities. These separation techniques form the basis of thermal smelting and refining operations.
