effect of ph on bornite flotation

Show full abstract sulfide into the oxide cycle of flotation increases pH of the pulp from 7 to 9 in the first case and from 8 to 10 in the second case which is favorable for an increase in

Feb 15 2020 · When the pH of the flotation system was 10 the recovery of Cu in the concentrate was the largest 9335 indicating that IBET has the best flotation effect on Cu at pH 10 As IBET dosage increases Cu recovery in the concentrate also increases The recovery tended to be flat when the dosage exceeded 17 gt

THE INFLUENCE OF pH AND OLEATE CONCENTRATION ON CHROMITE FLOTATION after Palmer enau and Aplan 1975 This chromite 2O 3 assayed 42 CrIII 8 Al 2O 3 4 FeIII 7 Fe II and 8 MgII with a PZC at about pH 7 Flotation response at high pH match the hydrolysis peaks of FeOH and MgOH respectively

Bornite recoveries tended to be depressed with a smaller amount of NaHS as pH increased The recoveries of chalcopyrite increased as pH increased at an optimum NaHS dosage Moreover the flotation kinetic model that includes the surface properties and the reaction rate constant between the copper sulfide minerals and NaHS was derived

1 Types of copper sulfide ore 1 Single copper mineral Its ore characteristic is relatively simple and the only useful component that can be recycled is copper The gangue minerals are mainly quartz carbonate and silicate 2 Coppersulfur ore Called copperbearing pyrite In addition to copper minerals iron sulfide can be recovered and the main mineral of sulfur is pyrite

Multiscale investigation of applying secondary effluent in sulfide flotation Water in Mineral Processing Proceedings of the 1st International Symposium 279290 Zhang J Ahmari S Zhang L 2012 Effects of activator typeconcentration and curing temperature on alkaliactivated binder based on copper mine tailings

The Effect of pH on Pulping and Flotation of Mixed Office Wastepaper MAD AZEVEDO J DRELICH and JD MILLER The effect of pulping reagents on the deinkingflotation of laserprinted wastepaper was investigated with regard to the removal efficiency of toner and mineral filler particles at different pH

Control of pH is one of the most widely applied methods for the modulation of mineral flotation In this study the effect of pH on potential in solution and sulphur minerals flotation is discussed with various electrodes The electrodes were platinum gold chalcopyrite pyrite and galena In solution potentials were linearly dependent on pH with a different slope for each electrode

conditions of pulp such as the pH type and concentration of reagents collectors depressants and frothers also are the effective factors on the process efficiency Hassanzadeh and Hasanzadeh 2016 evaluated the effect of three chemical reagent configuration on selective flotation in low and high pyritic copper sulphide ores

A detailed study was conducted to evaluate the effect of particle size pH flotation time collector type and addition on efficiency of tennantite flotation It was shown that maximum copper recovery of 953 was obtained at pH 123 by was suggested to grind up to 6572 of 0074 mm to achieve the optimum recovery of copper and high

THE EFFECT OF pH MODIFIER ON THE FLOTATION OF Keywords flotation pH modifier celestite calcite sodium oleate concentration ores 1 INTRODUCTION Somasundaran 1975 states that pH is the best factor with which to control flotation of most minerals and that selecting a suitable pH value is essential for mineral separation

This study was performed to determine if the flotation deinking process is first order with respect to ink particle concentration and to examine the effects that pH may have on the kinetics of ink removal flotation A Hallimond tube laboratory flotation device was used to examine the process Image analysis of ink particles was used to obtain quantitative results regarding flotation efficiency

ABSTRACT Flotation was proved to be effective for decarburization and removal of dioxins from hospital solid waste HSW incinerator fly ash but weathering makes it difficult The effects of three types of surfactants including nonionic Tween 80 anionic SDS and cationic CTAB at different pulp pH values on the flotation performance of weathered HSW incinerator fly ash were investigated

An example of testing the effect of pH on rougher flotation on pit samples and the results are presented Since this is only an example it needs reminding that not all ores will respond the same Here rougher flotation is most Selective at a pH of 95 as pH levels in the 9

125 pH of leach liquor is 1 The degree of copper leaching was about 60 which is exactly the participation of oxide copper forms regarding to the total copper content of the flotation tailings Mine waste water from the accumulation Robule were used as leaching solution with pH correction

also depressed at pH 11 32 Effect of pH on flotation Maintaining PAX and MIBC concentrations at 100 gt and 200 gt respectively flotation behaviour of Cu and Mo was investigated at varying slurry pH ranging from pH 3 to 11 and the results obtained are presented in Table 3 and Fig 3 Pulp density was maintained at 20 and flotation was

sulphide minerals Bornite Cu 5 FeS 4 and covellite CuS and energite Cu 3 AsS 4 are normally present in lesser quantities The complete flotation of chalcocite is achieved between ph 1 to ph 10 with ethyl xanthate The resulting hydrophobic species is CuX 1 Hydroxyl as depressant OH
