Oxidative pressure leaching is becoming the most popular hydrometallurgical technique for Molybdenum recovery because of its environmental friendliness and versatility in treatment of high/low-grade concentrates.Copper concentrates produced by froth flotation contain ca. 80% Cu-(Fe)-sulfides but are also enriched in many minor and trace metals (Ag, As, Bi, Au, Co, etc.) relative to ore feed; in many cases, those trace elements mostly occur in solid solution in the host sulfides or as included grains of discrete minerals.

molybdenum concentrate process

molybdenum concentrate impurities. 1 Introduction In China There are many porphyry copper deposits bearing molybdenum arsenic zinc and aluminum et al [1] [7] The copper concentrate is often obtained by conventional flotation process but those impurities of molybdenum arsenic zinc and aluminum usually exist in copper concentratesCopper, iron, and lead impurities are removed from molybdenum flotation concentrates by mixing the feed concentrates with a nonvolatile chloride salt, heating the mixture to a temperature of from about 200° to 350° C for a time sufficient to activate the lead impurities in the concentrates so that they can be leached therefrom during the subsequent leach step, and leaching copper, iron, and ...

Molybdenum belongs to the group of refractory metals.

Molybdenum belongs to the group of refractory metals and has a melting point of 2620 °C. Molybdenum is a by-product in the mining process of complex raw materials such as copper.

Box 1500 Logan Lake, British Columbia V0K 1W0 Emergency Telephone: CANUTEC(613) 6666 Supplier: Teck Highland Valley Copper ...Molybdenum is a chemical element with the symbol Mo. Pure molybdenum exists as a dark-gray or black powder with a metallic luster or as a silvery-white mass. It does not occur naturally in the pure metallic form. It is principally found as oxide or sulfide compounds. Therefore, almost all exposure is to a molybdenum compound rather than the actual metal alone.

Copper removal from molybdenite concentrate by …

1. Introduction. Molybdenite (MoS 2) concentrates are commonly obtained as byproduct in the treatment of copper porphyry ores in which the molybdenite is a minor constituent.The conventional process to separate molybdenite from the bulk copper–molybdenum concentrate is differential flotation, which includes successive recleaning steps in order to produce high-grade molybdenite concentrate.Molybdenum (atomic symbol: Mo, atomic number: 42) is a Block D, Group 6, Period 5 element with an atomic weight of 95.96. The number of electrons in each of molybdenum's shells is [2, 8, 18, 13, 1] and its electron configuration is [Kr] 4d 5 5s 1. The molybdenum atom has a radius of 139 pm and a Van der Waals radius of 209 pm.
