Magnetic domain observations on magnetite crystals in biotite and

[1] Magnetic domain structures have been observed on magnetite crystals in 300 μm to 1 mm size biotite and hornblende grains separated from drill core samples of Precambrian granodiorite basement in southern Alberta, Canada. The crystals were mounted in epoxy, and the surface was polished, first mechanically and then with a suspension of amorphous SiO 2.

Compared with magnetic induction, the magnetic induction gradient produced by the extruded magnetic system has a more profound effect on the capture process of biotite. Based on the comprehensive analysis results of experiment and simulation, we conclude that the capture mechanism of DMS on biotite can be divided into four processes ...

Biotite Mineral | Uses and Properties

The name "biotite" is used in the field and in entry-level geology courses because these minerals generally cannot be distinguished without optical, chemical, or x-ray analysis.. Biotite is a rock-forming mineral found in a wide range of crystalline igneous rocks such as granite, diorite, gabbro, peridotite, and pegmatite.It also forms under metamorphic conditions when argillaceous rocks …

Biotite refers to a group of common rock-forming minerals forming a series between phlogopite and annite. The name is best used as a field name for dark micas for which the exact composition has not been determined. It is found in a variety of occurrences. It occurs in plutonic igneous rocks ranging from granites to gabbronorite to syenites. Large crystals may form in …

Magnetic interaction in biotites and oxidised biotites

The magnetic moments in biotite appear to undergo a spin-flop or metamagnetic transition to a fer- romagnetic state on application of an applied field of ~-0.2 T parallel to the octahedral plane (Ballet and Coey 1982). While there is no symmetry (point group 1) at the Fe atom in biotite, Ballet and Coey (1982) have attempted to ...

Biotite Processing | Equipment, Process Flow, Cases

The high iron content, which imparts dark colors, rules out biotite from many industrial uses. However, because biotite is abundant in granitic rocks, pegmatites, and schists that are also associated with the more desirable muscovites, the mineral is important for exploration. Biotite is mica of little commercial value.
