Utilization of novel ester-containing quaternary ammonium surfactant as cationic collector for iron ore flotation

Flotation performances and adsorption mechanism of α-hydroxyoctyl phosphinic acid to cassiterite

“…The massive mineral samples were ground in an agate mortar and the fraction with a particle size ranging from -74 to +38 μm was selected as flotation feeds, and the artificial mixture ore was prepared by mixing cassiterite, magnetite and hematite samples at a weight ratio of 1:1:1. For FTIR, XPS Page 3 of 29 A c c e p t e d M a n u s c r i p t 3 and Zeta potential measurements, the finer fraction (-5μm) was used. HPA was synthesized according to Albouy's approach in our lab [11,12].…”

“…There was only 50%-70% fine cassiterite particles recovered through gravity separation technique [1]. As an alternative technique, flotation has been proved to be a more attractive method for recovery of fine cassiterite particles [2,3]. Previous investigations have found that fine cassiterite particles could be effectively floated out by using oleic acid or alkyl sulfate as a M a n u s c r i p t 2 collector [4][5][6].…”

Flotation of quartz using ionic liquid collectors with different functional groups and varying chain lengths

“…The hydrogen bond geometries and the adsorption energies as calculated using the density functional calculations for different amines and their derivatives on the quartz surface reveal that ester amines are stronger surfactants compared to the ether amines and primary alkyl amines . Many researchers have investigated the use of alternate economically viable collectors for the flotation of quartz (Yuhua and Jianwei, 2005;Weng et al, 2013;Xia et al, 2009;Araujo et al, 2005). Different new collectors such as aBromodecanoic acid, N-dodecylethylenediamine, gemini and commercial collectors like AERO 3030C, Flotigam DAT, and Armoflot 64 have been synthesized and applied for better separation of quartz and concentration of mineral values (Barbaro et al, 1997;Pereira and Peres, 2005;Liu et al, 2009;Luo et al, 2015;Sekuli et al, 2004 Ionic liquids which posses low volatility and high ionization temperature, have several applications in varied fields.…”

New Insights into the Adsorption of Oleate on Cassiterite: A DFT Study

“…Flotation is a separation technology taking place in aqueous media, whose success relies on regulating the wanted mineral surfaces hydrophobic using collectors and the unwanted mineral surfaces hydrophilic using inhibitors [36][37][38]. In flotation, cassiterite particles are firstly dispersed in water.…”
