Magnets can be used to remove magnetic minerals such as magnetite from concentrate. They can be used after or in conjunction with other method of concentration. One technique for extracting magnetic minerals is to place hand held magnets on the bottom of a pan containing dried concentrate to separate metallic from non metallic material

Jul 01, 2021 · Iron ore (coarse grade) Manufacture Current magnetite production is a by-product of the copper operations and as such is recovered from the Concentrator floatation tails stream by magnetic separation. Approximately 15%, by weight, of magnetite is removed by 'cleaning' and 're-cleaning' of the magnetic concentrate from the first stage. This results in the upgrading of magnetite to 66% Fe (greater than 95% magnetite)
