Molybdenum is a chemical element with the symbol Mo and atomic number 42. The name is from NeoLatin molybdaenum, from 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 other metals

6/1/2010· A direct hydrometallurgical process for molybdenum extraction and recovery from a Ni–Mo ore is reported. The novel technology includes leaching molybdenum by air oxidation in alkaline solution,purifying the leach solution with freshly precipitated "nascent" Fe(OH) 3 and "buffer agent" NCO 3, enriching molybdenum by ion exchange and crystallizing ammonium molybdate tetrydrate.

Molybdenum recovery in the fine and ultrafine and coarse fractions drops off to a greater extent than the recovery of copper. The investigations of degree liberation ore is the main reason for unstable froths and lowered frothing power. It has been shown that destabilization of frother takes place in the presence of

Molybdenum Recovery From The Copper Processing. Oxidative roasting is used to convert the iron oxide into insoluble hematite, and copper and molybdenum into the soluble form in acidic solution. since molybdenum is associated to iron oxide spinel type phase, its recovery was influenced by the magnetite content in the slag during the leaching process.

At both locations, the recovery of copper is the prime target; however, substantial quantities of molybdenum are also recovered. The molybdenumcontaining mineral (molybdenite) is obtained from the ore at the mines by a series of crushing, grinding and flotation operations, which produce a concentrate consisting primarily of the molybdenite

Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability.
