Ceramic Tiles

When fine iron and iron-bearing minerals contaminate the raw material used to produce ceramic tiles, the consequences are costly. Such iron contamination causes visual and structural defects as well as affecting the surface finish in terms of brightness and whiteness.  Tiles failing final quality checks are commonly returned for recycling. Those passing the initial quality…

Electrostatically Recovering Copper Wire

A combination of an ElectroStatic Separator and a Metal Separation Module is enabling the recovery of fine copper and other metals from a waste product at a UK metal recycling company. The Bunting ElectroStatic Separator, launched earlier in 2020, significantly enhances the ability of companies to recover fine metals such as copper wire.  In this…

Radial Magnetic Field Bunting Magnetics

Rotary Magnetic Separators, such as the Drum Magnet and Pulley Magnet, are designed with a specific type of magnetic field.  The type of magnetic field is considered when looking at any application and when deciding which design will achieve a customer’s separation objective. For these rotary designs of magnetic separator, there are two types of magnetic…

Iron-Specked_Ceramic_Tableware-0537

Fine iron and iron-bearing minerals cause visual and structural defects in ceramic tableware.  Such contamination appears as small dark spots on the surface or is hidden within the body and causes premature cracking of the ceramic.  The cup, saucer or plate is then either rejected or reworked. Iron contamination The problem of iron contamination is…

Sanitaryware is a commonly used term in the ceramics industry referring to sanitary appliances found in toilets and bathrooms.  Traditionally, bathroom bowls, cisterns, bidets, urinals and washbasins are made from porcelain (a ceramic material made from clay that might be described as ‘vitreous china’ when coated with enamel).  This might be referred to as ceramic,…

Electro magnetic filter

Successfully removing fine iron from ceramic slips and glazes is vitally important in any ceramics plant.  Such iron contamination is removed using high intensity magnetic separators like those on display on the Bunting and Master Magnets stand 1517 at the Ceramics UK show (10-11 July 2019, Telford, United Kingdom). Iron contamination causes surface defects (black…

Induced 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…

Aggregate Quarrying

Magnetic separators can be found in most mineral processing operations, especially those processing non-metallic minerals and magnetic ores.  This article investigates the use of high intensity magnetic separators and magnetic separation equipment in the minerals sector with a focus on processing dry materials (in the -15mm, +45 micron size range). Principles of Magnetic Separators There…
