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 MoreTwo New Overband Magnet Models
Bunting has added two new models to their popular and highly successful range of Permanent Overband Magnets. The two new designs – the PCB-C (Compact) and QBC (Quick Belt Change) – meet specific requirements of reduced maintenance time and lighter weights. These models expand the Overband range, which also includes the classic PCB model. The…
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…

One of the largest quarries in the US state of Georgia is protecting their processing plant against damage from tramp ferrous metal by installing a Bunting PCB1206-EL Permanent Crossbelt Separator. Junction City Mining helps build bridges in the US southeast by supplying high-quality aggregate materials for construction. The company required a massive structure to handle the…
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…
Read MoreAmerican Quarries Install TN77 Metal Detectors
TN77 Metal Detectors are proving popular with quarry operators in the USA. The industrial Metal Detectors identify tramp metal in conveyed aggregate and prevent damage to screens and crushers. The TN77 metal detector is a tunnel-type Metal Detector used widely in the quarrying, mining and recycling industries where the conveyed material is non-metallic or non-conductive. …
Read MoreRare Earth Roll or Induced Magnetic Roll
Comparing Two High Intensity Magnetic Separators High intensity magnetic separators remove ferro and para magnetic particles from dry non-metallic minerals. However, the design of the separation system dictates the final product purity and product losses. The two most common designs of dry high intensity magnetic separator are the Induced Roll (IMR) and the Rare Earth…
Read MoreDetecting and Removing Tramp Metal from Conveyors
The process of quarrying aggregate and mining ore often results in the introduction of tramp metal. The effective detection and removal of this tramp metal is critical to prevent damage to crushers, screens and conveyors, and is achieved using metal detectors and magnetic separators. The design of metal detector or magnetic separator is dependent upon…
