Most copper concentrates also contain small, but not insignificant, quantities of PGMs. These eventually find their way, together with gold and silver, into the copper refinery anodic slimes (see Chapter 36). Most large copper refineries, therefore, normally operate a precious-metal (PM) plant where anodic slimes are treated.
