They decided that, excepting iron ores, aluminum, and ferroalloys, electric smelting was in the experimental stage. It is the purpose of the present paper to survey the technical and economic changes that have taken place and to determine whether electric smelting of nonferrous ores offers any more promise today than 20 years ago.

Book digitized by Google from the library of Harvard University and uploaded to the Internet Archive by user : Secondary scrap smelters use blast furnaces, top blown rotary converters, and electric furnaces for smelting low-copper grade scrap. The main smelting product is molten black copper, which is converted to rough copper, then fire refined, and cast into anodes. Secondary copper refining is similar to primary copper refining.
