In 2011, approximately 13 million metric ... Froth flotation is part of a copper beneficiation process in which finely ground ore is placed in
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 …
1.Introduction. Molybdenite, as the main source of molybdenum, is mainly produced as a by-product from the flotation of copper ore deposits. For example, molybdenum is produced from copper‑molybdenum (Cu Mo) concentrates in the Las Luces Cu Mo beneficiation plant [1].This beneficiation plant mainly processes copper …
The beneficiation of copper-molybdenum ores is generally carried out by a two-stage flotation method. The first stage uses thiol collectors to recover copper sulfide and pyromorphite as a mixed ...
The second stage subjects the bulk copper–molybdenum sulfide concentrate to a selective flotation technique to separate molybdenite from copper sulfide. In the copper circuit, typically 1–4 kg/ton of lime is added to maintain an alkaline pH for the depression of pyrite. The calcium species releases into the solution from the lime could ...
The suggested combined method of cleaning of middlings of copper–molybdenum ores beneficiation provides the total copper recovery increase by 0.8% with a reduction of the cost price of saleable material by 0.5%. Introduction. A significant part of copper and molybdenum losses (about 15%) during …

In the world, from the point of beneficiation process, the copper ore deposits can be divided into the following main types [3, 4]: - porphyry ores occur very often, and it is estimated that more than 60% of the copper production comes from this deposit type. They are mainly copper-containing ores and copper and molybdenum ores.
In addition, the dissolved copper from copper oxidation might suppress the floatability of copper and molybdenum minerals. Mineralogical analysis shows that the …

separation is especially significant. In order to obtain more molybdenum in copper-molybdenum ore, it is necessary to scientifically and rationally choose and use the beneficiation process to achieve copper and molybdenum separation. 3.1.Single Molybdenum Ore Beneficiation Technology Molybdenum ore can be coarsely grounded.
The average production mass ratio of molybdenum to copper during 5 years is 3:100, which is used as the allocation factor in this study. Also, molybdenum is separated during the copper's beneficiation process. This means that the energy consumption during the mining and beneficiation will include two parts.
