Copper concentrate is fed into the ISASMELT furnace where it is heated to 1185 degrees Celsius This process melts the concentrate into liquid drawing out impurities and releasing sulfur dioxide gas which is captured and piped to the Incitec Pivot Acid Plant adjacent to our smelter stack for conversion into sulphuric acid used in crop4789
Copper was discovered and first used during the Neolithic Period or New Stone Age Though the exact time of this discovery will probably never be known it is believed to have been about 8000 bce Copper is found in the free metallic state in nature this native copper is the material that humans employed as a substitute for stone3697
