In Sungun copper-molybdenum processing complex, copper and molybdenum concentrates are recovered by flotation from porphyry ores with an average grade of 0.62% Cu and 0.01–0.02% Mo. The complex currently consists of two phases of copper processing, with a total input capacity (total capacity of phases 1 and 2) of 14 …

Silver tends to concentrate with copper and lead sulfides. AEROFLOAT® and AEROPHINE® silver flotation reagents are widely used to optimize silver recovery from concentrates. Our reagents for mineral processing are used extensively for the recovery of precious and base metals, including gold, copper, molybdenum, nickel and cobalt, …

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.

One of the challenges for the flotation of copper-molybdenum ores is the presence of copper sulphide minerals in molybdenum concentrate. Small grains of …

There are some important differences between the flotation of copper ores and other applications. First, several types of mineral species that contain copper can be found (CuFeS 2, Cu 2 S, CuS, Cu 5 FeS 4, and Cu 3 AsS 4, among others) which respond differently to the oxidizing and reducing conditions of the particulate system.

A copper–molybdenum iso-flotability flotation process has been developed to efficiently improve the recovery of molybdenite from Duobaoshan porphyry Cu–Mo ores. The effects of flotation ...

Molybdenite is the most important mineral resource for molybdenum, and it can be recovered as a byproduct from porphyry copper ores. Froth flotation, which is the …

Copper and molybdenum are important metal resources, efficient treatment and utilization of copper and molybdenum ores are of great significance to the development of economy and technology in the world. Flotation separation of chalcopyrite and molybdenite is an enormous challenge faced by mineral processing, since …

The copper ore in Chilean copper porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in the mining operation, it is common to …

Important strategic and commodity metals including, copper, zinc, lead, rhenium, and molybdenum are typically found in sulfide ores and less commonly in oxide-based ores, as is the case for aluminum. "What's typically done is you burn those in air to remove the sulfur, but by doing that you make SO 2 [sulfur dioxide], and nobody is …

These samples were then prepared for MLA analysis (e.g., mixing with resin, briquetting, and polishing). The MLA results were then used to calculate the recovery of each mineral in each copper-molybdenum ores. As we used five types of copper-molybdenum ores, the analytical work would be enormous and time-consuming.

Molybdenum was discovered by Carl Wilhelm Scheele in 1778, and was isolated and named by Peter Jacob Hjelm in 1781. 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 from copper mining.

This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in the mining operation, it is common to blend the ores mined from various spots and then process them using flotation.

Ores containing kaoline, brammollite, illite and montmorillonite were examined in the laboratory to determine how clay minerals affect the floatability of copper and molybdenum, and to find a ...

One of the challenges for the flotation of copper-molybdenum ores is the presence of copper sulphide minerals in molybdenum concentrate. Small grains of chalcopyrite (smaller than 50 μm), as well as pyrite, are the major impurities in the molybdenum concentrate. To a lesser extent, other copper sulphide minerals such as …

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. Making very pure moly concentrate grades is necessary for lubricant and oil additive applications so the ...

molybdenum ore, copper-molybdenum ore, and finely disseminated and ultrafine molybdenum ore, all of which with grades higher than 0.08%, are extremely difficult to beneficiate. Molybdenum ores with grades higher than 0.1% usually contain valuable metals such as lead, gold, and silver, so the practical

the copper–molybdenum ores beneficiation is an urgent one [28,29]. The main indicators of the flotation process—extraction and selectivity concentrate—when using collectors depend on the specificity of their interaction at the interface's solid–liquid (s-l) and liquid–gas (l-g). In this regard, researchers are focused on studying ...
