The effective recovery of valuable metals is an important step in the economic viability of recycling e-waste. Technology that maximises metal recovery and purity is the focus for Bunting on stand 110 at the E-Waste World Conference & Expo, taking place on 28-29 June 2023, Frankfurt/Germany. Bunting is joined on the stand by local representative Marcel Graef from 3SMI.

The nature of e-waste means that metal recovery often requires complex processing with specialist equipment and separation technology playing a key role in successful recycling. There are several stages of metal separation in a typical e-waste recycling plant, for which Bunting provide solutions. Ferrous metal recovery is commonly early in the process, with relatively straight-forward recovery using Overband Magnets, Drum Magnets or Pulley Magnets. These are both in standard strength ceramic ferrite and high-intensity rare earth magnet designs.

After removal of the magnetic materials, the focus turns to non-ferrous metals including aluminium and copper. Bunting developed the High-Intensity Eccentric (HIE) Eddy Current Separator to separate non-ferrous metals as small as 3 mm and often smaller. The remaining fine fraction is passed through an ElectroStatic Separator, which enables the recovery of metals such as fine copper wire.

To support companies who are developing e-waste recycling operations or are seeking to improve metal recovery rates, Bunting has a material test facility to assess separation capabilities. The Customer Experience Centre at Bunting’s Redditch facility in the UK is home to a wide range of metal separation equipment including the ElectroStatic Separator and Eddy Current Separator. “E-Waste has never held a greater value,” explained Bradley Greenwood, Bunting’s European Sales Manager. “The successful recovery of metals involves many stages of size reduction, screening, and separation. Our metal separators play a key role in that process, maximising the recovery of metal prior to more complex processing. We look forward to speaking with e-waste recyclers at the conference.”
