To meet the exponentially rising demand for lithium, it becomes vital to develop environmentally friendly processes its recovery from brines, salt lakes and/or seawater. In this work, novel composite lithium transport selective polymeric membranes were developed separate and magnesium ions. Hydrogen manganese oxide (HMO) (at weight percentage 0 25%), polystyrene sulfonate sodium (PSS–Na) trifla...

The study of the depression effect non-toxic depressants on flotation separation chalcopyrite from galena is great importance for both industrial applications and theoretical research. mixed depressant (DFinal) four common inhibitors—sodium carboxymethyl cellulose, sodium silicate, sulfite, zinc sulfate—exhibited high selectivity during galena. Flotation tests an copper–lead bulk concentrate sh...

We report on the wavelength-selective photopolymerization of a hybrid acrylate-oxetane cholesteric liquid crystal monomer mixture. By controlling sequence and rate orthogonal free-radical cationic reactions, it is possible to control degree phase separation in resulting interpenetrating networks. show that this can be used tune reflective color structurally colored coatings produced. Conversely...

The efficient separation of ultrafine coal is a challenging process due to the particle size and gangue entrainment. In this study, polymer, polyvinylpyrrolidone (PVP), was introduced as regulator for beneficiation. addition PVP improved combustible recovery clean decreased ash content. This effect also presented by selectivity index. regulation mechanism investigated using diverse methods. ads...
