Chromite crystals are mostly formed as small crystals or microcrystals, and large crystals are formed as multiple microcrystalline units
Chromite is a mineral used as the main source of chromium, a malleable metal. This mineral is actually a chromium oxide in the Chemical form of FeCr2O4. Chromite exists mainly in veins and small masses as an element of mother Rock and iron. Most of the chromium used in the Steel industry is to produce stainless steels and alloy steels. Chromium, as an alloy element in steel, gives high resistance to rust, corrosion and heat to steel. Chromium is used as a coloring agent in the production of paints, pigments and industrial dyes.
Chromite is found as Stone in nature. This stone is also known as chromite and contains chromium oxide with the formula FeCr2O4. Chromite occurs in mineral deposits and veins and may be found in the ground as small particles or larger deposits. Accumulations of chromite are found in some regions of the world including South Africa, Albania, Kazakhstan, Turkey and India.
Some chromium derivatives are also used in the production of electrical insulation and corrosion protection materials. Chromium is used in the production of car parts such as rims, noses and car mirrors. Due to the high resistance of chromium to rust and corrosion, it is used as a protective coating on Metal parts. Chromium is used as a coloring agent in the production of colored glass. Adding chromium to Glass can produce different colors, such as green glass, blue glass, and yellow glass. Chromium is used in the production of Aluminum alloys. Adding chromium to aluminum alloy can give high corrosion and heat resistance to aluminum.
Chromite mine identification can be done by examining some geological signs and symbols on the surface of the earth. Chromite ore is usually green to black in color due to the presence of chromium. Therefore, the presence of dark green or black masses in Rocks and surface soils can be a sign of the presence of chromite. Chromite is found as masses and veins in rocks. Therefore, if black or dark green lumps or streaks are seen in the stones, there is probably an indication of the presence of chromite. Chromite is mainly associated with parent rocks such as limestone slag, dolomite and bentonite slag. Therefore, the presence of these Stones near masses or dark green veins can be a sign of the presence of chromite.
Chromite has magnetic properties and may cause magnetic anomalies on Earth's surface. Therefore, the use of magnetic tools such as magnetic receivers can help identify areas of chromite potential. Chromite is usually black to dark green in color, but may also be red, brown, yellow, or gray in some cases. Chromite stone has medium to weak luster and in some cases it may be slightly opaque. Chromite crystals are mostly formed as small crystals or microcrystals, and large crystals are formed as multiple microcrystalline units.
Chromite stone has medium hardness and has a hardness of about 5.5-6 on the Mohs scale. The specific mass of chromite is about 4.5-4.8 g/cm3 and has glassy to glassy-rough fracture. Chromite has magnetic properties and can show magnetic anomalies. Chromite is composed of chromium oxide (FeCr2O4), which includes iron (Fe), chromium (Cr) and oxygen. Due to the presence of chromium, chromite shows good resistance to corrosion and chemical analysis
