Deutsches Kupferinstitut: Production of copper

In fire-refinement, impurities are removed in the air furnace by blowing air through "poles" of the liquid copper matte in the rotary kiln (anode furnace) where the last traces of sulfur are removed. During this process the oxygen content is reduced to between 500 ppm and 2000 ppm. In the past, the "poles" were reduced by the.
