Horne Smelter has the capacity to process 780000 tonnes per year of copper bearing material The CCR Refinery processes copper anodes which are converted into 9999 copper cathodes and sold on world markets It has been in operation since 1931 and is the only copper refinery in Canada It also has an integrated precious metals refining plant
The refining anodes taken out from the refining furnace is changed into electrolytic copper with purity of 9999 through an electrolysis process Slag Sand Since extraction of sea sand has been progressively banned due to consideration of the environment Slag Sand is drawing attention as a substitute for concrete fine aggregate material
Long afterwards smelting furnaces acquired the shape that they essentially maintained right down to Victorian Swansea days ie 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
The development of the anode furnace is based on Outotecs comprehensive experience of the smelting and refining processes Challenges in fire refining The conventional fire refining process consists of an anode furnace capable of treating blister to anode copper through oxidation by air and reduction by reductant eg natural gas LPG or diesel
