All of the North America mining operations are wholly owned, except for Morenci. FCX records its 72 percent undivided joint venture interest in Morenci using the proportionate consolidation method.
The removal of molybdenum from a copper ore concentrate by sodium hypochlorite leaching was investigated. The results show that leaching time, liquid to solid ratio, leaching temperature, agitation speed, and sodium hypochlorite and sodium hydroxide concentrations all have a significant effect on the removal of molybdenum.
How to separate copper & molybdenum; the problem. Molybdenum is found in small amounts in practically all low grade porphoritic copper ores. It is usually present as the sulphide, molybdenite, which is readily recovered in the copper flotation concentrate. Copper sulphide flotation concentrates may contain from 0.25 to 1.00% MoS2.

Molybdenum produced as a by-product of copper from copper porphyry deposits, like the Bingham Canyon deposit in Utah, is removed as molybdenum disulfate during flotation of the powder copper ore. The concentrate is roasted to make molybdic oxide, which can be put through the same sublimation process to produce molybdenum metal.
a copper concentrate, also known as molybdenum plant tailings.. The molybdenum plant tailings is final copper concentrate that is dried and sold. The bulk molybdenum concentrate proceeds through three further stages of flotation to achieve the desired molybdenum concentrate grade.
Özdoğu's copper and molybdenum production concentrates in its subsidiary, Kuze Ege Copper Enterprise Inc., currently Turkey's only molybdenum concentrate producer. They produce 50,000 tons of copper concentrate and 1,800 tons of molybdenum concentrate annualy.
In addition, Teck has a pipeline of copper projects in various stages of development. Our customers can be confident in our ability to ensure a long-term, reliable supply of quality copper and molybdenum concentrates. Concentrate production is a process where the main metallic compounds of the mine's ore are separated and 'concentrated'.
The resulting MoS2 concentrate usually contains 85%~92% MoS2 and small amounts of copper (less than 0.5 percent) if the molybdenum is recovered as a by-product of copper. Further treatment by acid leaching can be used to dissolve impurities like copper and lead if necessary.
To separate the molybdenite from the copper sulfides, the copper/molybdenum concentrate is run through a molybdenite recovery flotation circuit, in which chemicals are added to "depress" the copper, meaning to prevent the copper sulfide minerals from attaching to the froth, while the molybdenum …
The first commercial copper product, in an increasing chain of added value, is the copper concentrate, which main components are copper, iron and sulfide. During the same processing stage molybdenum, as bi-sulfide, is obtained, which is then processed to attain the commercial form of molybdenum trioxide.
KGHM International operates mines in Canada, the United States, and Chile and constructed the Sierra Gorda copper-molybdenum project in Chile and actively progressing with the Victoria project, the newest discovery in Sudbury, Ontario, Canada.
Oct 15, 2018· Molybdenum Concentrate Leaching at Highland Valley Copper. copper minerals out of the molybdenum concentrate in order to produce a saleable Option 1 eliminate leach plant, invest in additional flotation equipment to other impurities such as lead and zinc that must be …
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. ... Separation and upgrading the molybdenite from the bulk copper-molybdenite concentrate is generally ...

Thus a lead smelter or a zinc smelter could not smelt a copper concentrate (the converse is also true). In fact any copper in a lead or ...
The final copper product, the combined first cleaner and rougher tails, is filtered to -12% moisture and shipped by rail car to various smelters. The molybdenum concentrate averaging 43% Mo is spray dried in NIRO atomizing dryers and barreled for shipment.
Most of the molybdenum concentrate is roasted to convert the sulfide to oxide, which is known as Technical Molybdic Oxide. ... Everyone knows what copper and aluminum look like and can immediately identify a copper cable or aluminum can. But not many can look at a light bulb or a TV tube and tell which parts are made of molybdenum.

Selective leaching of molybdenum from copper concentrate by air oxidation was investigated in alkaline solution. • The leaching behaviors of Cu and Mo phase were predicted by Eh-pH diagrams of Mo-S-H 2 O and Cu–Fe–S–H 2 O system, respectively.. The oxidation mechanisms of sulfides in the copper concentrate were illustrated by methods of XRD and SEM-EDS.
The concentrate, which is now approximately 30% Cu and 0.35% Mo, is pumped to the molybdenum plant where the molybdenum disulfide is separated from the copper sulfide. Chemicals referred to as depressants are added to the pulp to reduce the flotation of the copper minerals while allowing the molybdenum minerals to float.
