Two Magnetic Disc Separators Process Coltan
A Nigerian mineral processor is installing two (2) Magnetic Disc Separators (MDS) to separate individual minerals in a Coltan plant. This latest export project reflects Bunting’s position as a recognised global leader for the design, manufacture, and supply of high-intensity magnetic separators for mineral processing. Technical product information: Magnetic Disc Separator Magnetic Disc Separators The…
Read MoreRare Earth Roll Separator for University of Birmingham
The University of Birmingham has purchased a laboratory-scale Rare Earth Roll Separator for their School of Metallurgy and Minerals lithium-ion battery recycling research facility. The high-intensity magnetic separator enables the separation of very weakly magnetic particles. Battery Recycling Research The Faraday Institution is funding the ReLiB (Recycling and Reuse of Li-ion Batteries) project researching the…
Read MoreThe Crusher’s Arch Enemy – Tramp Metal
Crushing quarried aggregate is a key process stage of most quarries and when recycling demolition waste. Effectively protecting the crusher from rogue tramp metal damage prevents production losses and repair costs. The wide range of available crushing technology enables the production of optimally sized aggregate. Whereas Jaw and Gyratory designs commonly feature as primary crushers,…
Read MoreElectromagnetic Filters for Ceramics
Since the first ceramics were produced, iron and iron-bearing minerals have caused defects. The problematic minerals occur naturally in the raw materials, with additional fine iron accidentally introduced during transportation, storage or processing. Effective removal often involves several stages of magnetic separation. However, the introduction of High-Intensity Electromagnetic Filters proved ground-breaking in terms of removing…
Read MoreRecycling Growth Dependent on Technology
Annual events such as the UK’s Recycling Week, the Global Recycling Day and Earth Day provide the perfect platform for reflection and planning. Successful and extensive recycling reduces the pressure on the planet’s finite resources, whilst also providing desperately needed environmental protection. Many experts predict that the failure to radically change the way waste is…
Read MoreGetting Metal Out of Pet Food
Ensuring Pet Food is metal free before it reaches the consumer is critical. However, reports of foods being recalled due to metal contamination occur several times each year. To assist processors and producers, Bunting has developed a series of typical plant flowsheets showing proposed locations for Magnetic Separators and Metal Detectors including a typical Pet Food Processing Plant.…
Read MoreMagnetic Properties of Ceramic Minerals
Magnetic minerals and fine iron have plagued ceramic producers since the first glazed pot was produced many thousands of years ago. Early ceramicists adopted elaborate and colourful patterns to cover any imperfections caused by such contamination. Over time, the demand for white or single coloured ceramic products increased, making disguising any imperfection increasingly difficult. Ceramic…
Read More6-Year-Old Electro Overband Magnet Refurbishment
Repair and refurbishment convert a well-used, functional magnetic separator into almost new, further extending the life of the equipment. One of Bunting’s latest repair and refurbishment projects involved a 6-year-old Electro Overband Magnet. The oil-cooled Electro Overband Magnet model 155 OCW 45 CB separates tramp ferrous metal from biomass pellets in a bulk handling terminal…
Read MoreWet High Intensity Magnetic Separation Testing
The electromagnetic laboratory-scale Wet High Intensity Magnetic Separator (WHIMS) removes fine magnetics and para-magnetics from mineral slurries. Handling minerals in a slurry or suspension is preferable for many processors, especially when beneficiation involves wet processing. Additionally, a wet process often produces a better separation for very fine materials. In this educational video, Professor Neil Rowson…
Read MoreMetal Recovery from WEEE and Cable
There is a wealth of valuable metals present in WEEE (Waste of Electrical and Electronic Equipment) and cables. However, the recovery is often difficult due to the small particle size range and variable nature of the metals. With the development and launch of the ElectroStatic Separator [in 2020], Bunting now provides a complete multi-stage metal…
