Magnetic separation process

Weakly magnetic mineral
Its material specific magnetic susceptibility X between (15 ~ 600)×10-6cm3/g g, in the magnetic field intensity H=480000 ~ 1600000 a/m PTMS magnetic separator can be selected. Most of these minerals are easy to select, and some are difficult to select. There are mainly: most iron manganese minerals - hematite, specularite, limonite, siderite, hydromanganese, pyrolusite, hard manganese, rhodochroite and so on; Chromite, black serpentine, olivine, garnet, pyroxene, etc.
Most of these minerals are paramagnetic and some are antiferromagnetic.

PTMS magnetic separator

Nonmagnetic mineral
The material specific susceptibility X is less than 15<10-6cm3/g. There are also many such minerals, mainly some metal minerals - chalcopyrite, galena, sphalerite, stimony, scheelite, cassiterite, gold, etc., most non-metallic minerals - sulfur, coal, graphite, diamond, gypsum, kaolin, etc., most rock forming minerals - quartz, feldspar, calcite, etc. Some of these minerals are paramagnetic and some diamagnetic. The so-called non-magnetic minerals are not absolutely non-magnetic, only very small. At present PTMS magnetic separator can achieve magnetic field intensity sorting.

what is magnetic separation in Feldspar？

The above classification is generally classified under modern technical conditions, because there are many factors affecting the magnetic properties of minerals, even though the magnetic properties of the same minerals are not completely the same in different places.
With the development of magnetic separation technology, the boundary between weakly magnetic minerals and non-magnetic minerals will change. The lower limit of the specific magnetic susceptibility of weak magnetic minerals is decreasing, which is the inevitable trend of the development of PTMS magnetic separator.
