Sep 26, 2018 · The remanence intensities of the mineral inclusions studied here indicate that the magnetic inclusions in feldspars and quartz are not important remanence carriers in oxic pelagic sediments; yet, they may be important in anoxic sediments where reductive diagenesis dissolves discrete magnetic minerals.

New thinking on wet magnetic treatment of feldspar ...

The feldspar could be milled to <100μ to liberate more of the magnetic particles and allow a finer matrix type to be used. Also, the material (0.5-1.2mm) could be pre-treated in a dry state with a Rare Earth Roll Separator to remove coarse free magnetic minerals prior to milling.

Is Feldspar magnetic? | Yahoo Answers

Oct 18, 2009 · Best Answer: Feldspar is not magnetic. There are two main varieties of feldpsars, potassium and plagioclase. Potassiums formula is KAlSi3O8, and Plagioclases is (Na, Ca)AlSi3O8. In order to be magnetic, they would have to contain iron. Neither contain any iron. Hope this helps.

Magnetite - Wikipedia

Magnetite is a rock mineral and one of the main iron ores, with the stone formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract …

Feldspar - Wikipedia

Feldspars are a group of rock-forming tectosilicate minerals that make up about 41% of the Earths continental crust by weight. Feldspars crystallize from magma as veins in both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are …

Feldspar Distinctions, Characteristics & Identification

How to Tell Feldspar. This lies between the hardness of a steel knife (5.5) and the hardness of quartz (7). In fact, feldspar is the standard for hardness 6 in the Mohs scale. Feldspars usually are white or nearly white, though they may be clear or light shades of orange or buff. They usually have a glassy luster.

Anisotropy of magnetic susceptibility in alkali feldspar ...

Jan 27, 2016 · The magnetic susceptibility of the feldspar samples is generally weak and ranges from −3.8 × 10 −8 m 3 kg −1 to +3.7 × 10 −7 m 3 kg −1 (Table B, Supporting Information). Seventeen specimens have negative mean susceptibilities and fourteen have positive ones.

Feldspar - an overview | ScienceDirect Topics

In iron ore, white gangue minerals include quartz, feldspar, and calcite. The magnetic susceptibilities of white gangue minerals are close to zero. It is therefore relatively easy to separate them from iron ores by magnetic separation.
