An investigation of the factors affecting the recovery of

Nov 01, · Bulk flotation molybdenum recoveries are consistently lower than that of copper as well as being far more variable. The objective of the work presented in this paper was to determine, and where possible prioritize and address some of the factors that contribute to the molybdenum recovery being lower than copper in the bulk flotation circuit at Kennecott Utah Copper.

Mineral Processing Solutions - WesTech Engineering, Inc

Copper / Molybdenum Flotation Circuit . 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. This separation

The Effect of Seaweed Glue in the Separation of Copper

Flotation separation of chalcopyrite from molybdenite was studied using seaweed glue (SEG) as a depressant. Flotation process and mechanism were examined by response surface methodology, flotation tests, adsorption tests, zeta potential measurements and fourier transform infrared (FT-IR) spectra. Response surface methodology with a Box-Behnken design suggested the optimal reagent schedule

Copper-Molybdenum ores

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.

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
