The company is involved in the mining, milling, and flotation of copper ore to produce copper and molybdenum concentrates; smelting of copper concentrates to produce anode copper
; and refining of anode copper
to produce copper cathodes, as well as molybdenum concentrate, refined silver and gold, and other materials
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.
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.
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.
Yi Xin Copper") whose primary operations are focused on reprocessing copper into brass, copper round rod and anode copper
, among other products, for industries including automobile and motorcycle manufacturers, electronics companies, cable companies, and producers of brass valves, which are used in plumbing and oil and gas production, among other uses.
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
Noranda's Canadian Copper Refinery ("CCR"), located in Montreal-East, Quebec, refines anode copper
from Noranda's Horne and Altonorte smelters, as well as other unrefined copper and precious metals from Noranda and third party sources.
