medium magnetic minerals includes most iron – manganese minerals like hematite, specularite, siderite, goethite, manganite, psilomelane, pyrolusite, rhodochrosite, etc.; and some titanium, chromium and tungsten-containing minerals, like ilmenite, rutile, chromite, wolframite, etc.; rock-forming mineral biotite, hornbeam, chlorite, epidote, garnet, olivine, pyroxene, etc.
These are some of the more common minerals that demonstrate magnetic properties: Babingtonite (weakly) Chromite (weakly) Columbite (weakly) Ferberite (weakly) Franklinite (weakly) Ilmenite (weakly, always when heated) Iron-nickel (attracted to magnets) Magnetite (strongly) Maghemite (strongly) Manganbabingtonite (very weak) Platinum (weakly)
The magnetic mineralogy of environmental materials such as sediments, dusts and soils, both modern and fossil, is often complex: therefore, contributions that advance the interpretation of natural magnetic mineral …
The magnetism of nonmagnetic minerals is very small. At present, the magnetic separator can not realize mineral processing, so it is called non-magnetic mineral. NOTE: With …

Magnetic minerals in rocks record the direction and intensity of the Earth's ambient magnetic field during formation, thereby providing information about past tectonic plate motion. In order to reliably interpret palaeomagnetic data, thermoremanent magnetization (TRM) and chemical remanent magnetization (CRM) mechanisms must be fully understood.
indeed, there is some literature about magnetic materials in the framework of gpr prospecting [2] [3] [4], and in particular it is thought that the soil of the planet mars can show magnetic...
The magnetic minerals in various rocks can in general be separated into five main categories: (a) Diamagnetic minerals have a small negative magnetic susceptibility due to the fact that the negatively charged electrons subjected to a magnetizing field H ⇀ alter their rotation rate to oppose the field. All magnetic materials exhibit this property, which is weakly affected by …
This study investigated the relationship between magnetic minerals and trace elements in the karst ditch wetland sediments. Sediment-bound magnetic signals, including χ LF, χ ARM, SIRM, and χfd% were strongly enriched and mainly altered by pedogenic processes.

The behaviour minerals exhibit in a magnetic field is classed under one of five headings: Diamagnetic; Paramagnetic; Ferromagnetic; Anti-ferromagnetic; Ferrimagnetic; These classifications define whether it is possible to separate one or more minerals from another using a magnetic separator.

Of all the minerals, by far the strongest (and important to geologists) is magnetite. For a brief description of that mineral, go to Geology. And for a fun, experiment-packed primer on all kinds of magnetism, go to Paul Doherty's lecture at the Exploratorium, 2000 Years of magnetism in 40 minutes.
Minerals like magnetite, pyrrhotite, ilmenite, maghemite, awaruite, and sometimes garnet, and peridot are attracted by magnets. Serpentinite and ironstone are two types of rocks of strikingly different origins that are also attracted by magnets. Iron is an agent that gives rise to magnetic properties.

Magnetic separation of minerals is a topic that is seldom reported in the literature for two reasons. First, separation data generally are byproducts of other projects; and second, this study requires a large amount of patience and is unusually tedious. Indeed, we suspect that most minerals probably are never investigated for this property.
Eight samples of the Chelyabinsk meteorite were studied using thermomagnetic and electron microprobe analyses; the hysteresis loop characteristics were also measured. The main magnetic minerals of the meteorite are represented by two groups of Fe-Ni alloys (native Fe minerals) with various concentrations of nickel and iron sulfides.
The magnetism of nonmagnetic minerals is very small. At present, the magnetic separator can not realize mineral processing, so it is called non-magnetic mineral. NOTE: With the development of magnetic separation technology, the boundary between weak magnetic minerals and non-magnetic minerals will change. The lower limit of the magnetization coefficient of …

Based on the magnetic susceptibility values in Table 9.1, iron minerals can be divided into two groups, namely strong magnetic minerals, that is, magnetite (72.4% Fe), and weakly magnetic minerals, that is, martite (70.0% Fe), hematite (70.0% Fe), specularite (70.0% Fe), limonite (57.14–59.89% Fe), and siderite (48.2% Fe). While magnetite ores are naturally suitable for …
