Table 5 presents the first order flotation rate constant, the maximum theoretical flotation recovery, and the coefficient of variation of the rate constant, obtained from the data of rougher flotation of a copper sulphide ore with 10% (w/w) biosolids, 1.5% (w/w) salt of humic acids, and a mixture of conventional collectors and frothers used in.
The flotation reagent of molybdenum ore uses non-polar oils as collectors, while adding foaming agents. the united states and canada use the surfactant syntex as an oil emulsifier. according to the nature of the ore, lime is used as a regulator, water glass is used as a gangue inhibitor, and sometimes cyanide or sulfide is added to inhibit.
Therefore, flotation process is the main beneficiation method for copper sulfide ore. the common collecting agent used for copper sulfide ore flotation process is xanthate collectors, followed by aerofloat and its esters. actually, the collecting effect is much better if.
Typically, rougher molybdenite flotation and recovery from bulk copper/molybdenum concentrates involves the use of alkalisulfides, nokes reagents, cyanides, oxidants, and/or thermal treatment to depress copper sulfide minerals. the bulk copper/molybdenum feed generally varies from 0.2% mo to 1.0% mo, and with traditional reagents the single-stage rougher flotation recovery of molybdenite.
