    Collectorless flotation of Chalcocite by controlling redox

    Using microflotation method this study explored the collectorless flotation of Chalcocite and its dependence on the redox potential of pulp . Electrochemical studies were performed by cyclic voltammetry in specific potential ranges and at different pH values. The results show that significant floatability of Chalcocite occurs in the specific reducing conditions.

    The flotation of chalcocite bornite chalcopyrite and pyrite has been studied in a microflotation cell in which the potential of a bed of the mineral particles could be controlled electromechanically. The ethylxanthate-induced flotation of each mineral is markedly dependent on electrochemical potential with the recovery changing from 0 to 100 pct in potential intervals of - 0.2 V.

    The wettability and floatability of oxidized chalcocite bornite and chalcopyrite with the conditions of sodium hydrosulfide NaHS dosages and pHs were studied by contact angle measurements and single and mixture mineral flotation tests. To evaluate the results of the flotation the flotation kinetic model for copper sulfide minerals treated by NaHS was derived.

    Nov 01 2017 The flotation behaviors of chalcocite and molybdenite as a function of TGA dosage are indicated in Fig. 5. Recovery of chalcocite shows a substantially descending tendency with addition of TGA while recovery of molybdenite is essentially constant with trivial decline. All this shows TGA is an effective inhibitor for chalcocite.

    Differential flotation of a chalcocitepyrite particle bed

    Chalcocite dissolution products had a deleterious effect on chalcocite-pyrite separation by activating pyrite so that it floated below the potential ≃ 0.13 V at which xanthate is oxidized to dixanthogen. A pyrite bed activated with a copperII sulfate solution exhibited a flotation response with a potential dependence between that of .

    All flotation machines can be arranged to provide an oxidising environment required by the reaction to render the sulphide mineral particles hydrophobic. However as indicated above if oxidation proceeds too far thiosalt and eventually sulphate may form from the sulfur oxidation which may react with a metal ion in the solution forming metal .

    Mar 01 2019 Micro-flotation tests were performed in order to investigate the flotation performance of malachite and calcite. Fig. 1 shows the flotation recovery of two minerals in the absence and presence of sodium sulphide when SBX was used as collector. As shown in Fig. 1 in the absence of Na 2 S the floatability of malachite and calcite using the SBX collector is weak.

    Nov 01 2017 The first principle theory was adopted to understand the difference of their surfaces and reaction between minerals and reagents. Results of flotation tests revealed that selectivity of emulsified kerosene is the best of three collectors in separation of chalcocite and molybdenite though the others also display excellent collecting properties.

    Aug 21 2012 Chalcocite responds well to flotation. In Nchanga though it is lost mainly to very coarse and very fine size fractions of the concentrator tailings. This is because Nchanga flotation feed contains atypically high proportions of these fractions even at a moderate 55 passing 74 micron grind a characteristic of Nachanga ore.
