Mining. Ore body of the copper-molybdenum deposit in the "Erdenetiin-Ovoo" stretches to the west from the east, 25 km in the length and 1.5-3 km in the width and consists of 4 main parts. The length of pit in the primary mining is approx. 2500 m, the width is approx.1500 m, the lowest level is 1265 m and the depth has been reached up to 120 m.
Approximately 50% of the world's molybdenum production comes from Cu–Mo ore as a by-product ( Bulatovic, 2007 ). The flotation recovery of molybdenite from porphyry Cu–Mo ore is consistently lower than that of the copper sulfides ( Bulatovic et al., 1998, Bulatovic, 2007, Triffett et al., 2008 ). In 2004, the price of molybdenum increased …
Results are presented from a study of thermochemical processing of copper-molybdenum concentrates by liquation smelting, which concentrates the rock-forming and ore components selectively in immiscible liquid phases. Optimal conditions for liquation smelting have been determined, under which the extraction of molybdenum amounts to …

Copper molybdenum ore, Experiment study, Copper molybdenum separation, Flotation. Abstract. Aimed at the ore characteristics,the flotation flowsheet of one—stage coarse grinding—bulk flotation of copper and molybdenum—regrinding of bulk concentrate—separation of copper and molybdenum was determined …
A combined flowsheet and a beneficiation process for bulk flotation middlings of copper–molybdenum ore have been suggested, which include middlings grinding, sulfide minerals flotation ...
The chemistry of the Tropezón ore is distinctly different from the other ore types as it contains higher amounts of sulphides, copper, molybdenum, magnesium, iron, cobalt, nickel, small amounts of gold but lower concentrations of Al, Ca, Na and Ti.
Porphyry Cu-Mo deposit is the main output source of copper-molybdenum ore, is also the main acquiring way of copper-molybdenum metal, In ore dressing process, the synthetical recovery of copper to be considered and molybdenum.
Armenia - A view of ore-processing facilities of the Zangezur Copper-Molybdenum Combine in Kajaran, August 12, 2019.
During the molybdenum upgrading process, often the cleaner concentrate is roasted to drive residual reagents off all the minerals in the Cu-Mo bulk concentrate to make a selective. separation easier. Download PDF >. The following Danafloat™ collectors should be considered for copper-molybdenum flotation: Danafloat™ 067.
The undesirable presence of copper in the molybdenum concentrate was identified as a key focus for the investigation by process mineralogy, which has a history of successful process diagnosis.
The Bingham Canyon mine, is located near Salt Lake City, Utah, US. It is the one of the world's biggest man-made excavation, open-pit copper mines.
In the present study, we carried out copper-molybdenum ore flotation experiments in the presence of pure and blend depressants. We investigated the ability of different depressant systems to substitute for NaCN in the selective flotation process on a laboratory scale.
In a copper- molybdenum processing plant, copper sulfide concentrate (such as chalcopyrite) is floated
Semantic Scholar extracted view of "A process mineralogy approach to optimize molybdenite flotation in copper – molybdenum processing plants" by M. Abdollahi et al.
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 …
While there is significant molybdenum mining production, a significant amount is recovered as a byproduct molybdenum in copper mines. The flow chart is standard bulk flotation of copper sulphides and molybdenite during the depression of iron ore and gangue in the hardest circuits and cleaner.
Molybdenum ore mainly includes molybdenite single ore, copper-molybdenum ore, molybdenum-containing polymetallic ore, etc. Flotation is the main method, sometimes combined with gravity and …
Molybdenite is a sulfide mineral and is often found in copper-molybdenum porphyry deposits, which is processed as a by-product of copper during the flotation process 10.
In the optimization and adjustment of the Duobaoshan porphyry copper–molybdenum ore beneficiation process, the iso-flotability process has been proven to beneficial for molybdenum recovery ( Lin et al., 2017 ). Applying this process effectively reduces reagent consumption during mineral processing operations.
Molybdenite recovery, on the contrary, may vary significantly from operation to operation, and also within different ore bodies in the same operation. Copper and molybdenum recovery data for a one year period of a typical porphyry copper flotation plant are reported in Fig. 1, showing high variability of molybdenum recovery with time.
The article discusses the results of research on improving the tech-nology of processing copper–molybdenum ores using a combined collector emulsion.
Hydrometallurgical processing of molybdenum middlings from Shatyrkul-Zhaysan cluster ore. [email protected](Received 25 July 2023; Accepted 02 February 2024)AbstractThis research investigates the hydrometallurgical processing of molybdenum midd. ings extracted from copper-molybdenum ore at the Shatyrkul …
Separation and upgrading the molybdenite from the bulk copper-molybdenite concentrate is generally accomplished by selective molybdenite flotation following copper and iron sulphide depression. Standard depressant schemes include high pH via lime addition, sodium hydrosulphide, Nokes reagent, etc. During the molybdenum upgrading …

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'. This concentrated material is then sold to smelters for further refining.
Introduction. Recovery of molybdenum in copper-molybde- num ore processing rarely exceeds 50%. At most processing plants, where mass fraction of molybdenum in ore is 0.01–0.02%, this element is considered to be accompanying and no special measures are taken to increase its recovery. However, in the case of Erdenet GOK, where the mass …
