Metal separation at E-Waste World Conference 2024
10.06.2024Maximising metal separation and recovery from e-waste is the focus for Bunting on stand C60 at the E-Waste World Conference and Expo (26 to 27 June 2024, Messe Frankfurt/Germany). The Bunting team is joined on the stand by their local representative Marcel Graef from 3SMI.

Recovering the valuable metals present in e-waste is challenging, involving liberation, sizing, and separation. Bunting’s separation equipment recovers ferrous and non-ferrous metals at various stages in the e-waste recycling process.
High-intensity magnetic separators, including the Stainless Steel Magnetic Separator, recover small and weakly magnetic metals including fragmented stainless steel. The remaining non-magnetic fraction passes over an Eddy Current Separator, which recovers the non-ferrous metals such as aluminium and zinc. The concentric and eccentric magnetic rotor designs of Eddy Current Separator enable recovery of non-ferrous metals down to 3 mm in size.One of the final processes uses an Electrostatic Separator to recover finer metallic particles. Separation occurs by induced an electrostatic charge into a conductive dry-liberated particle.
The location of a metal separator within an e-waste recycling process depends on the flowsheet, the feed material, and the separation objective. Bunting’s applications engineers work closely with e-waste recyclers to understand their process and recommend the optimum separator solution.
