The Specifications cover the dense media separation (DMS) magnetite. 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 ...
Figure 11.1: Principle of dense medium separation. Dense medium separation (or heavy medium separation (HMS), or the sink-and-float process) is applied to the pre-concentration of minerals, i.e. the rejection of gangue prior to grinding for final liberation. It is also used in coal preparation to produce a commercially graded end …

will be the maximum grade that can be produced by a physical separation, and so the 0% recovery end of the curve terminates at an assay less than or equal to the assay of the purest grains available in the ore. In the graphs shown in Figure 2, points that are higher and to the right show better performance than points that are lower and to the ...
The separation was achieved through a two-stage flotation process in a self-designed flotation column using TA and SL depressants: Stage A (10 min conditioning with 25 mg L −1 TA, no frother) resulted in the separation of PE with recovery and purity up to 100 and 95.84%, respectively.

Interlayers with partially replaced (up to 50–70% of the grain area) magnetite are quite often noted. Magnetite in the form of separate relict particles is present in the hematite matrix in the form of closed …
Separation of gibbsite from iron oxides such as hematite and magnetite is known to be extremely difficult due to the similarities in their surface properties. In recent years, Indian researchers reported a bioprocessing method for hematite–corundum (Al 2 O 3) separation[38-41]. It was reported that through the use of corundum-adapted strains ...
The contamination of sulfur emanating from pyrrhotite in magnetite concentrates has been a problem in iron ore processing.
