[Dorsey Alfred Lyon; Robert Mayro Keeney].   beratory or blast furnace for smelting copper ores is either excessive or prohibitive. The main points to be considered regarding the electric smelting of copper ores are whether the ores can be treated as successfully in an electric furnace as in a combustion furnace, and if so, whether they can be smelted at a reasonable : Dorsey A. Lyon, Robert M. Keeney.

manner in which the smelting of copper ores is conducted. Inasmuch as copper ores are smelted in one of two ways-that is, either in a reverberatory or in a blast furnace-it will first be necessary to ascertain if the conditions essential for the successful conduct of these two methods can be attained in the electric furnace. 10 SMELTING COPPER ORES IN ELECTRIC FURNACE. iron and one-half sulphur, and that chalcopyrite consists of one-third each of copper, iron, and sulphur. He then makes the necessary calculations to determine the weight of the matte that would be produced if this ore were to be smelted. Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag. Long afterwards smelting furnaces acquired the shape that they essentially maintained right down to Victorian Swansea days, i.e. a small stone or brick chamber with some means of pouring or ladling out the molten metal, a hearth below, and a brick chimney, usually low and stumpy, which provided an updraft and allowed the waste gases to escape.

situ leaching of copper ores; from an environmen-tal point of view, this is a questionable produc-tion route. Several different processes can be used for copper production. The traditional process is based on roasting, smelting in reverbatory fur-naces (or electric furnaces for more complex ores), producing matte (copper-iron sulfide), and con-. The results from a characterisation of buildup in an electric smelting furnace for treating copperrich feed material at the Boliden Ronnskar smelter in Sweden are presented. The aim of the work was to obtain better knowledge about the mechanisms behind the formation of the buildup. Lead in naturally found in many metallic ores and contribute to emissions during ore and metal processing (Table ).The leading causes of lead emissions in mining and mineral processing in the United States are lead smelters, primary and secondary copper smelting, and iron and steel can originate from nearly every smelting and refinery process including: milling, .   The reason we put fuel on this belt instead of ore is that much less fuel is required for smelting. One yellow belt of coal can feed furnaces! That's almost 14 arrays! However, a full belt of iron or copper is required on the other side.
