Molybdenum Ore Processing by Flotation
This molybdenum flotation circuit, based on 250-500 tons per 24 hours is designed for low-grade molybdenum ore having high-grade streaks and with pyrite-quartz gangue. It is also basically sound for many other friable sulphide ores, such as antimony, silver and even some lead ores.
Molybdenum Flotation - Mineral Processing & Metallurgy
A Molybdenum Flotation case study with about 6% of the molybdenum contained in the feed is present as an oxide form and about 90% of this is not recovered to the flotation concentrate. Recovery of molybdenum into the rougher concentrate varied between 90 to 95% at a concentrate grade of 2.5 to 3.7% molybdenum. The rougher concentrate can be upgraded to a marketable grade molybdenum concentrate …

(PDF) The Effect of Water Quality on Molybdenum Flotation
The effect of water quality on the grade and recovery of molybdenum flotation concentration from a molybdenite (MoS2) bearing ore containing approximately 0.2 percent by weight molybdenum has been...
Copper–molybdenum ores flotation in sea water ...
Laboratory rougher flotation tests were conducted with two samples of Cu–Mo ores in fresh water and in sea water as a function of pH. In both cases Cu recoveries were slightly lower in sea water than in fresh water for a wide range of pH (pH 7–12). Flotation of molybdenite was however strongly depressed in sea water at pH higher than 9.5.

Molybdenum Filter | Molybdenum Removal | Filtra-Systems
The Molybdenum is a by-product of the copper production. The Molybdenum filter was installed to process the clarifier overflow to remove any remaining solids prior to sending the water for use in the Molybdenum floatation circuit. The water has to be free of solids larger than 5 micron to ensure proper floatation of the Molybdenum.
Copper And Molybdenum Flotation - ristoranteilbettolino.it
Copper–molybdenum ores flotation in sea water. As Fig. 3, Fig. 5 demonstrate (Sample A and B), at pH > 9 the froth layer thickness measurements under rougher flotation conditions, are clearly lower when measured in sea water than in fresh water. Also the amount of water transferred to the froth is lower in sea water (Fig. 4, Fig. 6).All these ...

Elimination of adverse effects of seawater on molybdenite ...
Molybdenite (MoS 2), the predominant Mo-containing mineral, is generally recovered from Cu-Mo sulfides through froth flotation which is a water-intensive process and requires high volumes of water resources (Lucay et al., 2015).
The role of surfactants in the flotation of molybdenite at ...
The use of petroleum hydrocarbon as a collector for molybdenum sulfide improved metal recovery but necessitated the investigation of surfactants to produce a suitable froth for flotation at the Climax, Colorado mill of American Metal Climax, Inc. Up to December, 1958, 346 …
Molybdenum in Drinking-water - WHO
Levels of molybdenum in drinking-water do not usually exceed 10 µg/l (Greathouse & Osborne, 1980). However, in areas near molybdenum mining operations, the molybdenum concentration in finished water was reported to be as high as 200 µg/l. Tapwater concentrations as high as 580 µg/l have been reported in Colorado (Chappell, 1973).
OPTIMIZATION OF FLOTATION PARAMETERS FOR …
determined as 5.5–6.5 in molybdenum flotation, while molybdenite might be depressed at high pH due to calcium ions. Besides, the ferrous and ferric species at higher pH values caused depression of molybdenite too (Castro and Bobadilla, 1995). In this study, the determination of the flotation behavior of a molybdenum ore was

Molybdenum - Wikipedia
Most molybdenum compounds have low solubility in water, but when molybdenum-bearing minerals contact oxygen and water, the resulting molybdate ion MoO2− 4 is quite soluble. Industrially, molybdenum compounds (about 14% of world production of the element) are used in high-pressure and high-temperature applications as pigments and catalysts.
Method of flotation of copper molybdenum ores
The bulk concentrate is treated with oxygen at a temperature of 60-95°C, a pressure of 0.05-1.0 MPa and pH=11,0; selective flotation of copper and molybdenum concentrate emitting molybdenum concentrate with the separation of molybdenum in the foam product is carried out at a pH of 6.0-8.0 (RU, patent No. 2038859, CL B03D 1/02, 1990).
