fire refining of copper

Fire-refining gives copper second life - Nexans

For high conductivity, refining is usually done through an electrolytic process which produces extremely pure “cathode” copper from blister copper taken from smelting and refining furnaces. However, energy costs are high. Fire-refining achieves +100% IACS (International A Copper Standard) conductivity at a fraction of the price.

Fire refining - messergroup

During refining the blister copper produced in the converter is processed to high-grade anode copper with a purity of over 99% in fire or anode furnaces. Firstly, residues of less noble elements are oxidised and removed as slag (“oxidation phase"). In the subsequent “pole phase“ natural gas, methane, propane or an ammonia-containing gas ...
