The milled ore/gangue powder is mixed with a liquid and aerated in the flotation step. The less dense ore rises in the froth to be collected, while the gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide.

Molybdenite is a rare mineral composed of molybdenum and sulfur. It is the primary ore of molybdenum, with important amounts of rhenium sometimes produced as a byproduct. Molybdenite is also used as a solid lubricant to reduce friction between sliding metal parts.
Molybdenum is a chemical element with the symbol Mo and atomic number 42. The name is from Neo-Latin molybdaenum, which is based on Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of ...
Arc-related porphyry molybdenum deposits are a substantial resource for molybdenum metal and may have anomalous concentrations of tungsten. The deposits contain low-grade ore (0.03–0.22 percent molybdenum) as molybdenite, but are large-tonnage, making them amenable to bulk mining open-pit techniques. The mineralizing system usually has ...
Molybdenum Mining Methods. According to the value minerals contained in the molybdenum ore body and their grade, molybdenum mines are classified into three types: a), primary mines, where the recovery of molybdenite is the main goal; b), byproduct mines, where the recovery of copperbearing ores is the primary objective, and molybdenite mining ...

Molybdenum was discovered by Carl Wilhelm Scheele in 1778, and was isolated and named by Peter Jacob Hjelm in 1781. The most important ore source of molybdenum is the mineral molybdenite; a minor amount is recovered from the mineral wulfenite. Molybdenum commonly is recovered as a by-product or co-product from copper mining.
Molybdenum ore introduction:.

Molybdenum is a solid, shiny, silvery metallic element that is ductile and malleable. It does not occur naturally as a free metal, but usually in an ore known as molybdenite. Molybdenum has a very high melting point, which enables it to form strong, stable carbon compounds in alloys such as steel. As a result, it is an important industrial element.
Molybdenum and copper-molybdenum porphyries are mined by open-pit or by underground methods. Once the ore has been crushed and ground, the metallic minerals are then separated from gangue minerals (or the molybdenum and copper from each other) by …
These ores have a molybdenum content of approximately 0.5 percent by weight. The accompanying minerals are separated from the molybdenum using the so-called flotation process. After being subjected to this method, the concentrate contains on average approximately 85 % molybdenite (MoS2). This concentrate is roasted at 600 °C.
Background: There is a critical need to examine whether mining of molybdenum (Mo) ore will affect Mo absorption and translocation by plants at a community level. Methods: Indigenous plants and their rhizospheric soil (0-20 cm) growing in two different areas including the mining and the unexploited areas were collected from the Luanchuan Mo mine-one of the largest Mo mines in Asia.
