  • Copper-Molybdenum ores - Danafloat - Home

    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.

  • US5078860A - Sequential and selective flotation of sulfide ...

    A sequential flotation process for the separation of components of an ore containing sulfides of copper and molybdenum involves initially effecting selective flotation of the copper component directly from the ore by conditioning the ore with a combination of a source of bisulfite ion and causticized starch to produce a conditioned ore having a pH between approximately 5.2 and 6.2, and ...

  • Mineral Flotation Cell Exhaust System Upgrade - Chessor

    The operation mines and processes 130,000 mtpd of copper and molybdenum bearing ore and produces concentrates containing roughly a million pounds per day of copper and up to 27000 pounds of molybdenum per day. The ore goes through several stages of .

  • Copper Molybdenum Flotation depressant - Barium Sulphate ...

    Copper Molybdenum Flotation depressant. The standard flow sheet consists of bulk sulphide flotation of copper and molybdenite while depressing gangue and iron minerals in the rougher and cleaner circuits. Recovery of copper is by standard flotation reagents identified in the copper ore flotation description.

  • Froth flotation - Wikipedia

    For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic, requiring little or no addition of collector). The particular chemical depends on the nature of the mineral to be recovered and, perhaps, the natures of those that are not wanted.

    The ore is mined from an open pit, crushed, and fed to ten ball mills. The concentrator is divided into two parallel comminution-flotation sections, so that five ball mills feed each flotation section. Both sections consist of three bulk copper and molybdenum rougher flotation lines, and the rougher concentrate is transferred to a regrinding stage.

    Molybdenum Ores. The major ore mineral in these deposits is molybdenite (MoS2 ), which contains 60 percent molybdenum. Copper and tungsten—and, to a lesser extent, bismuth, beryllium, and tin—are found in various proportions in molybdenum ore. In addition, rhenium is always present in molybdenite.

    Molybdenum (moly) is often produced as a byproduct of copper mining. Copper is used for electronics, construction, and metal alloys. Moly is mostly used to make metal alloys, and as a catalyst. As markets need copper and moly, their ores are separated, concentrated, and sold separately.

  • How is Molybdenum Extracted - SAMaterials

    The molybdenum mineral recovered by flotation is molybdenite. The flotation agent uses non-polar oils as collectors, and a foaming agent is added. In order to ensure the quality of molybdenum concentrates, we need to further separate copper, lead, iron and other metal minerals and calcium oxide and carbon minerals from molybdenum concentrate, can use sodium sulfide, cyanide to inhibit iron copper and .

  • Molybdenum - Wikipedia

    Molybdenum-98 is the most abundant isotope, comprising 24.14% of all molybdenum. Molybdenum-100 has a half-life of about 10 19 y and undergoes double beta decay into ruthenium-100. Molybdenum isotopes with mass numbers from 111 to 117 all have half-lives of approximately 150 ns.
