Selective flotation separation mechanism of LFPs and
In this study, selective flotation separation of LFPs and graphite electrode material was achieved using CMC as a highly efficient inhibitor in mixed electrode …
Selective flotation of chalcopyrite from pyrite via seawater …
However, the flotation process faces many challenges, especially when low-grade ores frequently associated with other sulfides such as pyrite (FeS 2), deteriorating chalcopyrite flotation [8]. Therefore, maintaining a high selectivity in chalcopyrite separation from pyrite is beneficial to achieve a good quality of Cu concentrate.

1. Introduction. In recent years, with the increasingly stringent environmental requirements, more and more attention has been paid to the harmless treatment of the low-concentration heavy metal ions wastewater produced in the mining and metallurgical industry [1], [2], [3].Wastewater containing copper, cobalt, and zinc metal ions is usually …
Aggregating fine hydrophilic materials in froth flotation to …
This results in a low flotation rate and low recovery of value minerals although their surface may be highly hydrophobic. For the same reason, fine hydrophilic particles can be carried by water flow to entrain upwards into the froth phase and lower concentrate grade. ... Studies on selective flotation of smithsonite from silicate minerals …
Highly selective flotation separation of chalcopyrite and …
Thus, effectively separating chalcopyrite and pyrite under low alkaline conditions is an attractive trend in the flotation industry (Han et al., 2019, Liu et al., 2006). ... The selective flotation mechanisms of MDPE towards minerals were validated by UV–vis spectra of MDPE solutions with metal ions, zeta potential measurements, FTIR …

Advances in depressants for flotation separation of Cu-Fe
The flotation separation of Cu-Fe sulfide minerals at low alkalinity can be achieved using selective depressants. In the flotation system of Cu-Fe sulfide minerals, depressants usually preferentially interact with the pyrite surface to render the mineral surface hydrophilic and hinder the adsorption of the collector. This review summarizes …
A Century of Research Leading to Understanding the
The design and development of selective flotation collectors has been the key to the remarkable success of flotation in beneficiating complex, difficult-to-process ores. Sustained research efforts in the field over the past hundred years have led to delineating the scientific basis of selective mineral flotation in terms of the crystal …

The selective flotation of arsenopyrite from pyrite
Given the characteristics of low dosage and environment-friendly, SS is a promising flotation depressant with remarkable application prospects to remove arsenopyrite from pyrite concentrate. View ...
Low-temperature collector for smithsonite flotation: …
This study aims to determine the flotation recoveries of smithsonite utilizing three novel collectors: sodium lauryl fatty acid amide, dodecyl hydroxamic acid, and 2-ethylhexyl phosphate, as well as the traditional collector, oleic acid. These reagents were examined at various temperatures, dosages, and pH levels using microflotation experiments.
Selective flotation of Cu-Mo sulfides using xanthan gum as …
Conclusions. In this work, Xanthan gum (XG), a non-toxic and low-cost derivative of polysaccharide, was studied as a selective molybdenite depressant in the copper-molybdenum flotation separation. The flotation tests on single minerals revealed that molybdenite was effectively depressed by XG, while the floatability of chalcopyrite …
Advances in depressants for flotation separation of Cu-Fe
The flotation separation of Cu-Fe sulfide minerals at low alkalinity can be achieved using selective depressants. In the flotation system of Cu-Fe sulfide minerals, …
The depression of pyrite in selective flotation by different reagent
At low xanthate concentrations, pyrite flotation presents two maximums at around pH 4 and 8 with depression around pH 7. The high flotation yield at pH 4 is due to the formation of sulfur-rich products and dixanthogen (Leppinen, 1990, Wang and Forssberg, 1991, López Valdivieso et al., 2005).
The flotation of low-grade manganese ore using a novel …
Abstract. We designed and synthesized a novel linoleate hydroxamic acid (LHA) which demonstrated high selectivity and strong collecting capacity for the beneficiation of manganese ore by selective flotation. The performance of this LHA and oleic acid (OA) used for anionic froth flotation was compared, and the critical factors of …
Selective depression of low-molecular-weight
Flotation separation of ilmenite and forsterite is challenging owing to their similar natural floatability. In this work, low-molecular-weight carboxylated starch (LMWCS) was prepared as a selective depressant for forsterite and ilmenite separation via flotation. Compared with conventional natural starch, LMWCS has stronger depression on …

Flotation separation of feldspar from quartz using sodium
The physical and chemical properties of feldspar and quartz are highly similar, thus they cannot be easily separated effectively. In this work, the flotation separation of feldspar from quartz using sodium fluosilicate (Na 2 SiF 6; SF) as a selective depressant was investigated.Moreover, the influence mechanism of SF on the selective flotation …
Selective depression mechanism of locust bean gum in the flotation …
The selective depression mechanism of locust bean gum (LBG) in the chalcopyrite-pyrite flotation was investigated in this work. Micro-flotation tests suggested that the recovery of pyrite decreased significantly by the addition of LBG at a slurry pH of 8.0, while that of chalcopyrite was relatively unaffected.
