Primary Copper - HarbisonWalker International


The traditional process is based on roasting ores containing copper sulfide, smelting in an electric furnace to produce copper matte (copper-iron sulfide) and blister copper, which is further refined to cathode copper. Another common process, flash smelting, uses the energy released during oxidation of the sulfur in the ore.

Process Description - Smelting | Home


During the smelting process the liquid level in the furnace can rise and fall. Unlike a tuyere, the lance can be raised and lowered automatically or manually so that its tip is always where it is required. The products of the smelting ISASMELT™ process are tapped from the bottom of the furnace through a water-cooled taphole.

COPPER Copper production - TU Delft


The reverberatory furnace dominated copper matte smelting for much of the 1900s, because it was an excellent process for smelting fine concentrate from flotation. It is a fossil fuel fired hearth furnace for smelting concentrate and producing copper matte. The reverbs began to decline in the
