The analytical grade methyl isobutyl carbinol MIBC was used as a frother No collector was used The flotation gas was high purity synthetic air used at a flow rate of 8 L/min The process water specifications were used from the previous study Forbes et al 2022
The flotation results showed that the pyrite flotation recovery in the serpentine/pyrite flotation system recovered from % to % after the addition of 50 mg/L EDTMPA; zeta potential test adsorption test scanning electron microscope characterization SEM results showed that 50 mg/L EDTMPA made the surface kinetic potential of

In the flotation separation of nickel sulfide minerals from fine chrysotile or serpentine it was found that when the chrysotile content in flotation feed increased the yield stress rapidly rose up [24]; when the pulp yield stress exceeded the range of Pa range the flotation froth zone obviously thinned and the concentrate grade
Resources play an important role in the development of the country Thus it is necessary to focus on the efficient exploitation and recovery of the mineral resource [1] [2] Froth flotation has been always employed for the recovery of sulfide ores due to their excellent inherent floatability [3] [4] [5] As a typically magnesium phyllosilicate gangue serpentine Mg 3 Si 2 O
Serpentine Mg 3 Si 2 O 5 OH 4 as a magnesium rich phyllosilicate mineral often associates with complex sulfide ores as a gangue is a commonly used method for separating these sulfide minerals and serpentine Pan et al 2019 In sulfide ores processing serpentine breaks easily due to its low hardness and this size decrease causes
serpentine by flotation with particular attention to the change in the agglomeration states of brucite and serpentine after dif floated for 3 min with a fixed nitrogen flow rate of L/min The froth products m1 and tailings were sequentially dried and weighed and the SiO2 content β X ray fluorescence spectrometry in the foam
Pure mineral samples of pentlandite and serpentine were obtained from Jinchuan Gansu and Dandong Liaoning respectively The pentlandite and serpentine samples were ground and sieved to obtain −74 38 µm pentlandite and −10 µm serpentine which were used for sedimentation flotation TOC and XPS analyses
Serpentine a magnesium silicate mineral with positive surface charge in many sulfide ores around the world usually deteriorates the flotation behavior by covering the target mineral surface
In the current research work the flow behavior of a liquid liquid extraction LLE process in a serpentine microchannel was analyzed The simulation was performed using a 3D model and the
Therefore the pulp yield stress value a measure of net inter particle forces is considerably higher than that is typical in flotation According to this study the pulp yield stress decreases upon addition of H 2 SO 4 to the pulp which also correlates to the extent of serpentine dissolution The continuation of fiber dissolution is
In this work the dispersive effect of low molecular weight sodium polyacrylate PAAS on serpentine and its dispersion mechanism were systematically investigated through zeta potential measurements micro and batch flotation as well as adsorption tests At pH 5 where flotation of iron sulphide was routinely performed pyrite and serpentine minerals were
Ecologix Technologies Asia Pacific Inc provides a number of technologies relating to water and wastewater treatment most with the pre fix Eco ; include internally and externally fed rotary drum fine screens a pipe flocculator a dissolved air filtration DAF technology enhanced with lamella separators a range of disc and tube membrane diffusers and
The flotation separation between sulfides and fine serpentine has always been a difficult problem due to their hetero coagulation To acquire a better understanding on the adverse effect of fine serpentine on Cu Ni sulfide flotation rheology measurements and flotation tests on Cu Ni sulfide/serpentine system were explored under different conditions in this study
Experiments To evaluate the aggregation of serpentine on pyrite surface a novel experimental protocol was designed and the aggregation behavior and mechanism in the absence and presence of sodium isobutyl xanthate SIBX were explored through in situ optical microscope micro flotation contact angle zeta potential and FT IR Afterwards the
system as a function of particle shape almost a reverse trend was obtained for the shape and flotation of serpentine in the mixture compared to a single serpentine system Thus at roundness values of chromite particles from to the flotation recoveries of chromite in the mixture increased from % to %
Abstract Four kinds of serpentine with different grain size were selected and the modified Hallimond tube was used to investigate the effect of conditioning time on the recovery of brucite and serpentine By analyzing the properties of pulp pH Mg 2 concentration Zeta potential contact angle and pulp viscosity the water solubility of serpentine and its effect on the
Flotation tests indicate that SA can further increase the difference in recovery rates between pentlandite and serpentine based on SHMP Results from artificial mixed ore tests demonstrate that the recovery rate of serpentine decreases from % to % with the addition of SA with minimal impact on the recovery rate of pentlandite
