Froth Flotation (Sulphide & Oxide) As new mineral of molybdenum observed in the feed, a decrease in recovery would happened This stage in bulk flotation of copper-molybdenum and usual reagents are utilized According to Paul Ramdohr (1980, The Ore Minerals and Their Intergrowths, Page 878)
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
Copper-Molybdenum ores Molybdenite (MoS2) is the predominant economic molybdenum mineral While naturally very hydrophobic and can effectively be floated with just frother, addition of a hydrocarbon oil extender enhances its recovery
Copper and molybdenum are accompanying minerals Almost over 20 percent molybdenum is recovered from copper and molybdenum Copper and molybdenum ore, which are mainly copper ore, is existed as porphyry copper with high recovery value and low grade of molybdenum (001~01%)

Buenavista del Cobre is a copper-molybdenum mine located in the state of Sonora, Mexico The mine has two concentrators: Concentrator 1 is a 90 ktpd plant which has been in operation since 1986 while Concentrator 2 is a 100 ktpd brand new plant design that started-up in 2014
1 Introduction The selective separation of copper–molybdenum sulfide minerals by flotation mostly relies on the use of various depressants Sodium hydrosulfide, sodium sulfide, cyanide and Noke’s reagent (thiophosphorus or thioarsenic compounds) are routinely used as the selective depressants of chalcopyrite (Bulatovic, 2007, Pearse, 2005
Optimization of flotation parameters for beneficiation of a molybdenum ore 525 found in low-grade ores and associated with copper sulfides
Froth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash
