differences in magnetic properties of various minerals present in the ore body. The magnetic fraction may be valuable or gangue depending upon its end use in a particular process and so also the non-magnetic fraction, e.g., separation of magnetite (magnetic) from quartz (non-magnetic), separation of tin bearing mineral cassiterite (non-magnetic)
Magnetite is a black, opaque, magnetic mineral that leaves a black streak when rubbed across a hard rough surface. It is one of the most abundant metal oxides, and its crystal structure contains both the ferrous (Fe+2) and ferric (Fe+3) forms of iron ions.

Oct 13, 1981· After removal of the weakly magnetic minerals there remain, when treating scheelite, merely nonmagnetic minerals, e.g. quartz, which can be separated in the flotation without difficulty. The invention is explained in the following in greater detail by way of a diagram shown in the drawing.
Scheelite occurs in vein/stockwork, skarn or stratabound deposits. Depending of formation of the deposit, the main gangue minerals are quartz, sulphides, calcite, apatite, fluorite, mica, talc, pyroxenes and amphibolites. Scheelite is very often finely disseminated in the ore, so that flotation is the main concentrating process.
