Separation based on the magnetic attraction felt by ferrous metals and eddy current magnetic repulsion felt by nonferrous metals. Gravity Separation based on the different specific weights of the various elements constituting a material stream.
Magnetic Separation. Ferromagnetic minerals are themselves magnetic (, magnetite and pyrrhotite) and can be easily separated from other minerals with a magnet since they will stick to the poles of the magnet. These minerals can be separated by wrapping the poles of a magnet in paper, passing the magnet over the mineral mixture.
Apr 25, 2016· The best quality ore has minimum 60% of iron. Lesser quality grades are treated, or refined to exclude several contaminants prior feeding the ore into the blast furnace. This refining method is known as beneficiation and includes more steps, such as crushing, washing, and magnetic separation, pelletizing, and sintering.
The optimum beneficiation resulted from the reductionroasting process of lowgrade manganese ore in 40+60 mesh at temperature 700°C followed by the magnetic separation process.
mineral . The results of a gravity separation of Itakpe (Nigeria) iron ore by jigging indicated that the iron recovery increased with decrease in particle size . This present study investigated the response of Baban Tsauni (Nigeria) leadgold ore to jigging separation, multigravity and shaking table separation.
Mar 01, 2012· First, uniform fine particle sizes are produced through the crushing and grinding process. And then magnetic separation is most commonly used to separate natural magnetic Copper ore from various lessmagnetic or nonmagnetic materials. Sometimes, gravity or flotation method maybe used instead of magnetic separation.

Wet High Intensity Magnetic Separation (WHIMS) test work and Wilfrey table test work on RC chip samples indicates that hematite (oxide) ore from the BooLoo – Dolphin prospect is amenable to upgrading. WHIMS at a magnetic strength of 10,000 Gauss and 212µm grind produced a concentrate containing ~60% iron with ~5% SiO2. Iron recovery was ...

The following picture shows the coarse disseminated quartz gold ore from South African, in the picture we can see gold grains clealy, and there are obvious boundary bewteen quartz and gold, of course, they have different specific gravity. For this coarsegrained disseminated gold rock, flotation machine is not the best mineral processing method.
