dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate [CaMg(CO3)2]. Along with calcite and aragonite, dolomite makes up approximately 2 percent of the Earth's crust. The bulk of the dolomite constitutes dolostone formations that occur as thick units of great areal extent in many …

Iron ore. Iron ore can be found in a multitude of forms and sources. The primary forms of iron ore today are Hematite and Magnetite.While iron ore can be found throughout the world, only the deposits in the order of millions of tonnes are processed for industrial purposes. The top five exporters of Iron ore are Australia, Brazil, South Africa, Canada, and Ukraine.

The recovery of strategic metals such as rare earth elements (REEs) requires the development of new sorbents with high sorption capacities and selectivity. The bi-functionality of sorbents showed a remarkable capacity for the enhancement of binding properties. This work compares the sorption properties of magnetic chitosan (MC, prepared by dispersion of …

Iron Ore: Iron ore deposits are quite rich in India. Magnetite is the purest iron ore, having a high iron concentration of up to 70%. It possesses exceptional magnetic properties. The most significant industrial iron ore is hematite ore. It contains between 50 and 60 percent iron. Some of the major iron ore belts in India are:

Fluorite is another mineral where the apparent color can be different from the color of the streak. Specimens of fluorite can be green, yellow, purple, blue, or colorless. However, all specimens of fluorite have a white streak. Specimens of pyrite always have a brassy yellow color; however, all specimens of pyrite produce a black streak.. Related: The Acid Test

The photos below show minerals common in metamorphosed iron formations. The hematite shown in Figure 8.58 is specular hematite (more common hematite has a red earthy color). Actinolite, seen in Figure 8.59, is a calcium-iron amphibole. Grunerite (Figure 8.60) is an iron amphibole. Greenalite (Figure 8.61) is an iron-rich variety of serpentine.

Chromite is a chromium-iron oxide found in pods or veins in bodies of peridotite and serpentinite. (Look for brown streaks.) It may also be segregated in thin layers near the bottom of large plutons, or former bodies of magma, and is sometimes found in meteorites. It may resemble magnetite but rarely forms crystals and is only weakly magnetic.

The magnetic compass is the most familiar compass type. It functions as a pointer to "magnetic north", the local magnetic meridian, because the magnetized needle at its heart aligns itself with the horizontal component of the Earth's magnetic field.The magnetic field exerts a torque on the needle, pulling the North end or pole of the needle approximately toward the Earth's North …

These elements can exist in their pure forms (as metallic iron and gaseous oxygen), but when mixed, they tend to react to produce magnetite (Fe 3 O 4), or hematite (Fe 2 O 3), perhaps creating minerals like the ones seen in the two photos here (Figures 4.27 and 4.28).

Scheelite is a calcium tungstate mineral with the chemical formula Ca W O 4.It is an important ore of tungsten (wolfram). Scheelite is originally named after Swedish chemist K. Scheele (1742-1786). Well-formed crystals are sought by collectors and are occasionally fashioned into gemstones when suitably free of flaws. Scheelite has been synthesized using the Czochralski …
