Description
Natural gas firing of copper shaft melting furnaces is the most economical and environmental method of melting refined or semi-refined copper. This concept is valid in terms of the mass of carbon used per ton of scrap or cathode copper raised to casting temperature when comparing available electrical and fossil fuel fired melting and liquid transfer processes. The comparative economics of electrical, shaft, and reverberatory melting of copper are explained here and compared for varying charge materials and initial energy sources.
