In total, Asarco's three open-pit mines and the Hayden smelter in Arizona produce 300-350 million lb (663-774 kt) of anode copper annually.
With the furnaces and converters, more than 300,000 t of anode copper can be produced annually from copper matte.
Some specific topics include heat exchange within the working space of an electric nickel anode refining furnace, new casting methods for anode copper, pyrometallurgical refining of copper in an anode furnace, and minor element control by vacuum calcination and recycling of copper smelter dust.
Anode copper is produced which is then refined into cathode under a tolling arrangement ahead of sale to other parties.
It processes 800,000 tonnes of copper and precious metal-bearing materials per year, yielding 180,000 tonnes of anode copper and 600,000 tonnes of sulphuric acid.
Exports of copper concentrates ceased in 1983 and current exports include around 30,000 t/y of anode copper, 15,000 t of cathod copper, plus about 2,900 t/y of molybdenum concentrates.
Thus in 1990, output comprised 92,000 t of anode copper of which some 30,000 t were exported.
Production capacity at the smelter in Harjavalta will increase from 165,000 tonnes to 210,000 tonnes of anode copper, while production at the tank house in Pori will increase from 126,000 to 153,000 tonnes of cathode copper per year.
The greater part of the excess anode copper produced at the Harjavalta smelter will continue to be processed at the tank house in Ronnskar.
The anode copper will be refined at Noranda's Canadian Copper Refinery (CCR) located in Montreal East, Quebec.
The Hayden smelter produced 200,000 tons of anode copper in 1994, the last full year for which production figures are available.
Production from Magma's smelting operations, which includes copper processed from Magma's mines and from third parties, was 199 million pounds of anode copper.
