Molybdite is a mineral that belongs to the family of oxides and hydroxides. Its chemical composition consists mainly of molybdenum, oxygen, and hydrogen, with the chemical formula MoO3·H2O. It typically forms as thin, tabular, or lamellar crystals, or in powdery masses. The mineral commonly occurs in various shades of yellow, ranging from pale yellow to lemon-yellow.
Molybdite is usually found in the oxidized zones of hydrothermal molybdenum-bearing deposits. It is formed as a secondary mineral resulting from the alteration of primary molybdenum minerals. It is also known to be found in association with other minerals such as quartz, molybdenite, and wulfenite.
This mineral possesses characteristic physical and chemical properties. Its hardness ranges from 1.5 to 2 on the Mohs scale, indicating its relatively low hardness. Molybdite also has a white streak, and its luster is described as pearly to dull. In terms of its chemical reactivity, it is insoluble in water and does not easily dissolve in acids.
Molybdite holds some importance in various industrial applications. Due to its molybdenum content, it can be utilized in the production of steel alloys, catalysts, and lubricants. Additionally, it serves as a source of molybdenum in the extraction process of this element for further industrial use.
Overall, molybdite is a mineral with significant commercial value, mainly due to its molybdenum content and its applications in various industrial sectors.
