    use or used to extract oxide ores of copper by leaching. Blister copper from the smelter is poured into the anode casting moulds. The anodes are cast into slabs about 1 metre square with arms at the top corners for lifting. (Courtesy of Codelco.) The anode casting turntable moves slowly round. The anodes can be lifted out at the far side.
