Magnetic separation: building the attraction

摘要

^The magnetic matrix separators well known to industrial minerals processors have recently ventured into unknown territory. These units, the Wet High Intensity Magnetic Separator, and the High-Gradient Magnetic Separator, have broadened their scope of treatable feed characteristics and do so with improved machine designs. The upgrades, specifically to the Cryofilter~R and SLon~R separators, allow for a broader range of ore types to be treated - types that were recendy considered inseparable or uneconomic. The Cryofilter, Outotec's superconducting high gradient magnetic separator, has expanded its applicability outside of fine kaolin brightening to treat much coarser particle sizes (up to 300um). This means operations previously left wanting for higher strength magnetic separators: mica, silica sand and zircon to name a few, can now benefit from the up to 5 Tesla strength provided by the Cryofilter.
