A novel pH-responsive flocculant for efficient ScienceDirect
1. Introduction. Copper (Cu) and molybdenum (Mo) have been listed as strategic metals by USA, European union, China, etc., and efficient recovery the metals from the mineral resources is a necessary approach to ensure the safe supply of Cu and Mo (Luo et al., 2021).However, as the increasing demand of Cu and Mo and continuous Abstract. Adsorption of poly (ethylene oxide) (PEO) of high molecular weight from water on to various forms of silica has been investigated and correlated with the varying degrees of flocculation produced. Both effects are most marked with silicas which carry “isolated” silanol groups and hydrophobic groups (either methyl or siloxane).The mechanism of adsorption of poly(ethylene oxide) flocculant

An experimental study on the flocculating settling of unclassified
The slurry concentration of the unclassified tailings in the experiments was 6.0%. Firstly, tailings and water were added to 1000 ml measuring cylinder and mixed for 1 min to obtain the slurry with a concentration of 6.0 vol.%. Then, the flocculant solution was added with a pipette and stirred for 20 seconds.Due to the nature hydrophilic of the copper tailings particle surface and the long main chain of NPAM flocculant, lots of water molecules are wrapped in the formed flocs, which reduce the settling velocity and increase the sediment volume [42], [46], as shown in Fig. 12 (a) and (b).Enhanced flocculation and sedimentation of copper tailings by

Preparation of carboxymethylated lignin-based multifunctional
A novel amphoteric lignin-based multifunctional flocculant was synthesized by “grafting to” strategy. • With the dosage of the lignin-based flocculant between 3.0 and 4.2 mg L −1, the turbidity removal rate for 0.5 g L −1 kaolin suspension reached more than 98% within 2 min.. The flocculant exhibited excellent co-sedimentation performance for Polyethylene oxide (PEO) has served as an effective flocculant in several systems [1,2]. However, the exact nature of the mechanism of polyethylene oxide adsorption remains unexplained. Rubio [3] found that poly-ethylene oxide was an effective flocculant on substances recognized to be hydrophobic but the polymer was ineffective on hydro-Flocculation of Oxides using Polyethylene Oxide Columbia

anionic polyacrylamide (PAM) and polyethylene oxide (PEO). The IR data were compared with general trends in the performance of the polymers observed during flocculation. These studies will help to understand the bonding between the precipitate and polymer and indicate the effectiveness of a flocculant for dewatering.Flocculation in water treatment refers to the process of smaller particles in water coming together to form larger masses called flocs. Flocculants are the substances used to encourage the process of creating flocs. Both flocculation and coagulation treatment chemicals are used in effluent wastewater water treatment processes for solids removalFlocculant and Coagulant Water Treatment ChemTreat, Inc.

Water Soluble Polymer Flocculants: Synthesis, Characterization,
The systematic development of a flocculant relies on a good understanding of flocculation process, polymer synthesis, polymer as well as surface complex formation between iron oxide and copper. The model could describe and predict the effects of various key operational parameters on the adsorption process, such as initial pHphenol, ammonium, phosphine. The harm of heavy metals such as copper, lead, zinc, chromium, mercury and arsenic and their compounds was well known. Water-soluble polyacrylamide (PAM) has been widely used as a flocculant in this field[2]. Mineral processing wastewater was required to be purified to meet the environmental standards ODPLGH IOPscience
