Spence is operated exclusively by BHP, and has produced copper cathodes by microbial leaching. The deposit contains reserves of copper oxides (1.14% Cu, mainly as atacamite; Cu 2 Cl(OH) 3) and copper sulfide ores (1.12% Cu, primarily supergene chalcocite and some minor amounts of covellite; CuS).These are mined and processed …

The processes for extracting copper from the two types of ore are quite different from each other, and the WF blue of the sulfide ore refining process is 2.4 times higher than that of the oxide ore refining process (i.e., 96 cubic meters per metric ton [tonne] of copper versus 40 cubic meters per tonne of copper).
