Minerals | Special Issue : Chromite Deposits: Mineralogy ...

Ore chromite coexists with high-magnesian olivine (4-6 % Fa), enriched by nickel, 0.6-1.2 wt.%. In accessory early stage chromite, found in all rock types, the Cr2O3 and MgO contents are low, and Al2O3 is high, caused by the more basic host rock composition and high-temperature conditions of the chromite crystallization.

Titanium Ore

Titanium ore was first discovered in 1791 in Cornish beach sands by an English clergyman, William Gregor. The actual identification of the oxide was made a few years later by a German chemist, M.H. Klaproth, who gave the metal constituent of this oxide the name titanium, after the Titans of Greek mythology.

Ore minerals

Titanium - Usually produced from placer deposits, the ore minerals are rutile, ilmenite, and leucoxene. Tungsten - Primary ore minerals are scheelite and huebnerite-ferberite. Uranium - The chief primary ore minerals are uraninite, pitchblende (a mixture of various oxides), coffinite and a host of secondary minerals such as carnotite and autunite.
