Flotation separation of bastnaesite from monazite using depressant dextrin hydrate and its depression mechanism

Weiwei Wang et al.

Summary: In this study, an environmentally friendly depressant, dextrin hydrate (DH), was introduced for the flotation separation of bastnaesite from monazite. The results showed that the recovery of monazite decreased significantly in the presence of DH, while the recovery of bastnaesite only exhibited a slight reduction. The mechanism was found to be related to the adsorption of DH on the Ce sites of monazite, which had a strong effect on the subsequent adsorption of the collector on the surface of monazite.

Flotation separation mechanism for secondary copper sulfide minerals and pyrite using novel collector ethyl isobutyl xanthogenic acetate

Yingqiang Ma et al.

Summary: This study investigates the collectivity and selectivity mechanisms of ethyl isobutyl xanthogenic acetate (EIBXAC) as a novel collector in the flotation of secondary copper sulfide minerals. The results show that EIBXAC has a better collecting effect on covellite and digenite compared to ammonium dibutyl dithiophosphate (ADD). The artificial mixed-mineral experiment demonstrates that EIBXAC can improve the grade of copper concentrate while maintaining the same recovery, indicating higher efficiency and selectivity. The adsorption and DFT calculations confirm that EIBXAC chemically adsorbs onto the mineral surface, with stronger adsorption capacity for covellite and digenite than ADD.

Synthesis of selective heteroatomic collectors for the improved separation of sulfide minerals

Wanjia Zhang et al.

Summary: The study synthesized chelating collectors based on heterocyclic thioketone framework and investigated their selectivity and mechanism through flotation experiments and theoretical calculations. The results showed that non-ionic collectors displayed better selectivity and weaker collecting ability, while strong ionic collectors exhibited the opposite behavior. This research not only revealed the potential of thioketones as selective sulfide collectors, but also provided a selectivity model based on bonding and charge transfer characteristics for further development of more selective sulfide collectors.

Adsorption behavior of sodium oleate on iron minerals and its effect on flotation kinetics

Huili Han et al.

Summary: This study systematically investigated the adsorption behavior of sodium oleate on hematite, limonite, and siderite and their corresponding flotation performance. The results showed that Fe atoms were the main active centers for the chemisorption of NaOL, with hematite and limonite having more active sites for NaOL adsorption compared to siderite.

A molecular analysis on nitrile-based collectors and their application to chalcopyrite flotation

Bijan Taheri et al.

Summary: This research investigates the adsorption properties of a newly designed nitrile-based collector on the surface of chalcopyrite through theoretical calculations. The results show that replacing the long hydrocarbon chain of the collector with a phenyl ring improves the adsorption efficiency. The new-designed collectors exhibit higher adsorption ability compared to the traditional collector. Collectors with the acronyms Tf(Ph)-3-R5, Tf(Ph)-N-2R1, and Tf(Ph)-N-2R2 show promising potential as alternatives to the traditional collector in chalcopyrite flotation.

Insight into the effects of grinding media on the flotation kinetics of chalcopyrite

Xiaolong Zhang et al.

Summary: The grinding medium significantly affects the flotation performance of chalcopyrite. Grinding with ceramic balls results in better performance due to the reduced presence of FeOOH on the chalcopyrite surfaces. Flotation kinetics models are useful for evaluating the performance of chalcopyrite flotation.

Chemical stability of xanthates, dithiophosphinates and hydroxamic acids in aqueous solutions and their environmental implications

Martha Araceli Elizondo-Alvarez et al.

Summary: Xanthates are commonly used collectors in mineral processing, but their instability and generation of toxic carbon disulfide have led to a search for safer alternatives such as dithiophosphinates and hydroxamic acids. These alternative collectors show greater chemical stability and may be considered environmentally friendly reagents, making them important for adoption in mineral processing.

An ion-tolerance collector AESNa for effective flotation of magnesite from dolomite

Wengang Liu et al.

Summary: The study successfully separated magnesite and dolomite by using an ion-tolerance collector, which showed better collecting ability and selectivity under alkaline conditions and selectively inhibited approximately 15% recovery of dolomite by Ca2+. The mechanism analysis revealed that the collector had a high surface activity and complexed with Ca2+ by electrostatic interactions to prevent interference in the flotation process.
