Exempel på hur man kan använda CHROMITE i en mening

• The mineral assemblage is greater than 90% olivine, with minor amounts of other minerals such as pyroxene, chromite, magnetite, and pyrope.
• The compositions of peridotites from these layered igneous complexes vary widely, reflecting the relative proportions of pyroxenes, chromite, plagioclase, and amphibole.
• Uvarovite most commonly occurs in solid solution with grossular or andradite, and is generally found associated with serpentinite, chromite, metamorphic limestones, and skarn ore-bodies.
• Chemical analysis of the microscopic chromite crystals, or chrome-spinels, retrieved from micrometeorites in acid baths has shown that primitive achondrites, which represent less than half a percent of the MM reaching Earth today, were common among MMs accreting more than 466 million years ago.
• On output-value basis, India was one of the five largest producers of mica, chromite, coal, lignite, iron ore, bauxite, barite, zinc and manganese; while being one of the ten largest global producers of many other minerals.
• Most of the chromite ore production was smelted in electric-arc furnaces to produce ferrochromium for the metallurgical industry.
• The town is endowed with rich mineral resources like aluminous laterite ore, chromite, gold, niceliferous laterite, sand and gravel, guano, rock phosphate, limestone, and siliceous sand.
• The major metallic mineral found in the municipality is chromite and the non-metallic includes semi-precious stones.
• It occurs associated with cooperite, braggite, sperrylite, other minerals of the platinum group elements and chromite.
• Minor constituents are schreibersite, troilite, chromite, pyroxenes, and phosphates (whitlockite, stanfieldite, farringtonite, and merrillite).

• Copper chromite is produced by the exposure of copper barium ammonium chromate to temperatures of 350-450 °C, generally by a muffle furnace:.
• For example, bauxite is used as flux for blast furnaces, while others such as wolframite, pyrolusite, and chromite are used in making ferrous alloys.
• It is a rare secondary mineral formed by hydration or alteration of the primary nickel and iron bearing minerals, chromite, pentlandite, pyrrhotite, and millerite, during the serpentinization of ultramafic rocks.
• Banket grew as a service centre for the surrounding mines and commercial farms, and has suffered from the downscaling of chromite mining in Zimbabwe.
• Gangue, typically quartz, magnetite, garnet, chromite and kyanite, which usually account for the remaining bulk of the THM content.
• Other minerals include Fe–Ni, troilite (FeS), feldspar or feldspathic glass, chromite, and phosphates.
• Oregonite is known, apart from its type locality, from the Chirnaisky Massif, Russia, associated with hydrothermal nickel minerals (millerite, heazelwoodite) in a metamorphosed ultramafic; from the Skouriatissa mine, Cyprus, associated with VMS mineralisation; and from the Kidd Mine, Timmins, Ontario, Canada within serpentinite-hosted chromite deposits.
• The primary minerals identified in Lunar regolith are plagioclase, olivine, augite, orthopyroxene, pigeonite, ilmenite, chromite, quartz, cristobalite, and whitlockite.
