Comparison of Adsorption of Phenol O-O and N-O Chelating Collectors at the Malachite/Water Interface in Flotation
To separate one base metal mineral from another by flotation, it is indispensable to identify chemical reagents that specifically interact with the surface metal sites of one mineral or a group of minerals. This work studies the interactions of chelating collectors which offer the best potential for collecting abilities and mineral specificity with a typical refractory oxide mineral (malachite)...
متن کاملFlotation of zinc silicate ore: A focus on effective parameters, synergistic effect of mixed cationic collectors and its mechanism
The present study addresses the direct flotation route for the concentration of a zinc silicate ore. Flotation of hemimorphite faces some challenges due to the similarity of hemimorphite and quartz surface properties. XRD, and XRF analyses, optical mineralogy and SEM with X-ray mapping were performed for characterization. The results showed that the quartz, hemimorphite, calcite and dolomite ar...
متن کاملInvestigation of Flotation Parameters for Copper Recovery from Enargite and Chalcopyrite Mixed Ore
A flotation pre-treatment study for the separation of enargite (Cu3AsS4) from chalcopyrite (CuFeS2) ores of different origins was investigated in this work. The copper ore bearing enargite mineral contained 5.87mass% As and 16.50mass% Cu while the chalcopyrite bearing ore contained 0.32mass% As and 21.63mass% Cu. The two ore samples were mixed at 7 : 3 (enargite : chalcopyrite) by weight ratio ...
متن کاملMalachite green induces genotoxic effect and biochemical disturbances in mice.
BACKGROUND AND OBJECTIVES Malachite green (MG) is a triarylaminmethane dye used in the fish industry as an anti-fungal agent. Concern over MG is due to the potential for consumer exposure, suggestive evidence of tumor promotion in rodent liver, and suspicion of carcinogenicity based on structure-activity relationships. In order to evaluate the risks associated with exposure to MG, we examined t...
متن کاملStability relations of malachite and azurite
Stability relations of malachite and azurite are calculated and shown in Eh-pH diagrams, using AF (Gibbs free energy) values listed in Garrels and Christ (1965). The malachite/azurite transition is very sensitive to small chemical changes in the environment: equilibrium is reached at Pco2 = 10-a4s atm., i.e. close to normal values, whereas the precipitation of both minerals from cupric-ion-bear...
