ElectroStatic Separation of Minerals
Article written by Neil Rowson, Professor of Minerals Engineering in the School of Chemical Engineering at the University of Birmingham Electrostatic phenomenon dates back to 600 – 700 B.C. when people noticed static electric effects (attraction of hair) when amber was rubbed with fur. Indeed, the word ‘electrostatic’ comes from the ancient Greek word ‘electron’…
Read MoreNew ElectroStatic Separator
The launch of the new Bunting ElectroStatic Separator is in response to enhanced material separation requirements in the recycling, plastics and minerals industries. The ElectroStatic Separator uses tungsten electrode wire to generate electrostatic charges to separate dry liberated particles. The new technology significantly broadens separation capabilities, opening up new opportunities for recovering materials from waste…
Read MoreSeparating Fine Iron from Powders
Effectively separating fine iron from dry powders is often challenging. Even the strongest magnetic separator may fail to successfully remove the magnetic particles. In order to find a successful solution, it is important to understand the way fine materials behave. Only then is it possible to determine the optimum method to cleanse a powder of…
Read MoreMagnetic Disc Separator Processes Beach Sands
Bunting’s latest Magnetic Disc Separator (MDS) is for processing and separating key minerals from a beach sands deposit. The three-stage Magnetic Disc Separator is destined for a mineral processing operation in Africa. The Magnetic Disc Separator Magnetic Disc Separators (MDS) enable an accurate separation of minerals with varied magnetic susceptibilities. Typically, a Magnetic Disc Separator…
Read MoreTramp Metal Removed from Reclaimed Kaolin
A major UK mineral processing company has installed two large Bullet Magnets to remove tramp ferrous metal from dry reclaimed kaolin. After initial discussions, Bunting conducted controlled tests in the Redditch Centre-of-Excellence. The reclaimed kaolin had a broad particle size range, with 95% below 250 microns. Iron contamination was approximately 1000ppm (although it could peak…
Read More3 Overband Magnet Installation Problems
The Permanent Overband Magnet is one of the most commonly used magnetic separators. Overband Magnets are found in most recycling plants recovering steel cans and other ferrous metals from a wide range of waste materials as well as in quarries (protecting crushers & screens) and on mobile plant (screens and crushers). However, incorrect installation leads…

Bunting distributors from across Europe converged on the Redditch site for the inaugural European Sales Conference. The two-day event included classroom and practical training on a wide range of magnetic separators and metal detectors. On day 1, there was a focus on equipment for the recycling sector. This included permanent and electromagnetic Overband Magnets, Pulley…
Read MoreNew XRF Enhances Mineral Testing Capabilities
The purchase of a new X-ray fluorescence (XRF) analyser enhances the mineral testing capabilities of the Bunting test laboratory based at the manufacturing facility in Redditch, UK. Hitachi High-Tech Analytical Science, based in Abingdon, UK, supplied the X-MET8000 Expert XRF analyser and provided comprehensive training for the technical staff at Bunting. The Science of X-Ray…
