Fines Copper Sorting

Copper granulate, recovered by the recycling process of copper wires and cables, has the potential to be a high value resource. However, even after the removal of impurities, polymers and ferrous from the granulate, it can still contain small amounts of lead, brass or aluminum – often up to three percent. TOMRA sorting technology removes the remaining pollutants efficiently and automatically from the copper granulate – with an especially high efficiency of lead removal.

Common copper sorting technologies, such as eddy current sorters or densimetric tables, do not remove all impurities. TOMRA Sorting has developed an innovative sensor-based copper sorting solution which removes the granulate's remaining pollutants efficiently and automatically, and is particularly effective at extracting lead. The copper sorting machine uses optical free fall detection and high speed air jets to separate the materials.
