Slide 21: Avoid deep mechanical treatment of high grade materials
Avoid deep mechanical treatment of “high grade” materials Every separation step bears the risk of co- separating (losing) precious metals. This can add up to significant PM-losses. Accepting higher impurities of Fe, Al and PM-loss % plastics in the Cu/PM-fraction generated in pre-processing can boos
