An aluminium dross processing plant in the Middle East has purchased an Eddy Current Separator, Drum Magnet and ElectroStatic Separator to recover the valuable metal. The separation equipment was designed and built by Bunting at their Redditch manufacturing facility in the United Kingdom. Aluminium dross is a byproduct of the aluminium smelting process. After crushing, mechanical separation enables the recovery of residual aluminium from the aluminium oxide. The first stage of the project involved Bunting conducting controlled material separation tests on three samples at their Customer Experience Centre in the UK. Each sample had different particle size ranges. The tests, undertaken on a range of laboratory-scale separators, confirmed the amount of aluminium that could be recovered by using three different types of equipment.The test concluded that a three-stage separation process effectively recovered the metal from the dross. The first stage of separation focused on removing magnetic particles with a high-intensity Rare Earth Drum Magnet. Magnetics accounted for approximately 1%. Removing the magnetics is beneficial to subsequent processing. The second step focused on separating small pearls of aluminium from the dross. An eccentric Eddy Current Separator recovered 14% aluminium from the dross. For the finer sized fractions, the remaining material was passed through an ElectroStatic Separator. Separation occurs by induced an electrostatic charge into a conductive dry-liberated particle such as aluminium. The ElectroStatic Separator recovered a further 6% of aluminium. The tests concluded that approximately 15% of aluminum could be recovered from the dross using a combination of the three separators.
