magnetite vs biotite chemical formulas

2010/11/16Both chemical formulas have iron in the so why is magnetite mined as an iron ore but biotite is not? Magnetite is a Oxide while Biotite is a sheet silicate. The liberation process is easier for the oxides while the Biotite is more difficulter because of the silicate.

Magnetite I grains are characterized by being textually inhomogeneous. The Magnetite I core (with local ilmenite exsolution lamellae) is Ti-Cr rich, indicative of a dominantly igneous origin. The Magnetite I core and its surrounding primary igneous minerals (biotite

2016/7/29Hello everyone! I have what might be a bit of a stupid question for the seasoned geologists/ petrologists (assuming there are any) on this forum: In a thin section, how do you distinguish biotite from brown hornblende WITHOUT using polarized light, WITHOUT seeing cleavage (I know that an amphibole would have a cleavage of about 120/60) and WITHOUT seeing any idiomorphic grains?

2.4 Silicate Minerals The vast majority of the minerals that make up the rocks of Earth's crust are silicate minerals. These include minerals such as quartz, feldspar, mica, amphibole, pyroxene, olivine, and a great variety of clay minerals. The building block of all of

2020/8/26When biotite weathers, it can become dark golden or coppery in color. People have found golden flakes of weathered biotite in sand and, as with fool's gold (pyrite), thought that this was real gold. This silvery clear color is characteristic of thin sheets of muscovite.

THE BIOTITE MINERAL GROUP Biotite is a very common form of mica. It is named in honor Jean Baptiste Biot (1774 - 1862), a French physicist, mathematician, and astronomer who researched the mica minerals for their optical properties. Because of Bio

The Eastern Tianshan Orogenic Belt of the Central Asian Orogenic Belt and the Beishan terrane of the Tarim Block, NW China, host numerous Fe deposits. The Cihai Fe deposit (gt;90 Mt at 45.6 % Fe) in the Beishan terrane is diabase-hosted and consists of the Cihai, Cinan, and Cixi ore clusters. Ore minerals are dominantly magnetite, pyrite, and pyrrhotite, with minor chalcopyrite, galena, and
