copper remove from molybdenum concentrate processing

Copper removal from molybdenite concentrate by sodium

May 01, 1998· 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. As a result of the many steps involved in the production of molybdenite concentrate, the recovery of molybdenum is low.

Copper Removal from Molybdenite by Sulfidation-Leaching

The process involves a sulfidation of the molybdenum concentrate with 82(g) at 380 °C followed by a leaching stage. H 2 SO 4-NaCl-O 2 leaching of a sulfidized concentrate containing 3.4% Cu for 90 min at 100°C produced a molybdenite concentrate with less than 0.2% Cu, which is appropriate for marketing. Molybdenite dissolution was negligible

Molybdenum removal from copper ore concentrate by sodium

Jan 01, 2011· The removal of molybdenum from a copper ore concentrate by sodium hypochlorite leaching was investigated. The results show that leaching time, liquid to solid ratio, leaching temperature, agitation speed, and sodium hypochlorite and sodium hydroxide concentrations all have a significant effect on the removal of molybdenum.

Process for recovering molybdenum and copper from sulfide

A hydrometallurgical process is provided for the recovery of molybdenum values from a molybdenum disulfide concentrate containing copper. The process comprises forming an aqueous slurry of finely divided molybdenum concentrate of carbonates and hydroxides of alkali metals, and pressure leaching the slurry in the presence of oxygen at an elevated temperature and pressure for a time sufficient

Copper and Molybdenum Flotation Process Xinhai

Copper and molybdenum flotation process is commonly used for copper and molybdenum ore with pretty high grade, while it’s rarely adopted in industrial production. In part combined flotation process, molybdenum with high floatability will be concentrated first, and then copper and molybdenum combined concentrate are concentrated together.

Review Molybdenum Recovery from Mineral Raw Materials by

Molybdenum (sulfide and oxidized), copper-molybdenum and uranium ores as well as secondary raw materials are the sources for molybdenum production. In 1940-1970, the pyro-metallurgical methods (Zelikman, 1970) were used for molybdenum breakdown from sulfide ores and concentrates. These methods are environmental dangerous and do not allow to isolate

Selling Metal Concentrates: Payable Metal, Treatment

By way of example, a copper concentrate could include chalcopyrite (CuFeS2), containing 34.6% copper, possibly another sulphide such as pyrite (FeS2) and other waste (or gangue) minerals. The overall grade of the concentrate could be in the range 22% to 30% copper. Concentrates are usually specific to particular smelters.
