molybdenum recovery from the copper processing

Uranium and molybdenum recovery from copper leaching

Mar 01, 2019· The typical impurities from the hydrometallurgical process of copper cathodes production, in this case, iron and zinc represent the main impurities present. Under these working conditions, they show anionic behavior, similar to uranium and molybdenum. Zinc recovery was 39.8%, while iron was 8.2%.

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 Key technological process Method of processing and Mo recovery from solutions Salt

US4444733A Process for recovering molybdenum and copper

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

Low Molybdenum Recovery in Bulk Copper-Moly Flotation Circuit

In a flotation locked cycle test, a poor/low moly recovery was obtained at 47.3% as it appeared that molybdenum had not reached equilibrium. The calculated head grade trend, shown in Figure 8-28 indicates that the moly and most of the other elements had not reached convergence when the test was terminated. Figure 8-29 shows the trend in recoveries as the cycles were executed. Moly recoveries

Copper-Molybdenum ores Danafloat

Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability.
