O-isopropyl-N-ethyl thionocarbamate (IPETC) collector was used to selectively recover elemental sulfur from a high-sulfur residue, and its flotation performance, structure–property relationship adsorption mechanism were studied. The raw ore test showed that IPETC displayed superior performance the compared with sodium ethyl xanthate (SEX) ammonium dibutyl dithiophosphate (ADDTP) collectors. Pur...

Поли-N-винилкапролактам (ПВКЛ), синтезированный полимеризацией с обратимой передачей цепи по механизму присоединения–фрагментации применением ксантатов для макромолекулярного дизайна, подвергается деполимеризации при нагревании в присутствии низкомолекулярного агента передачи - [1-(О-этилксантил)этил]бензола. Показано, что после активность 1-(O-этилксантил)этильных групп сохраняется и полимериз...

Accelerator functional character was introduced on nanosilica by chemical reaction of sodium isopropyl xanthate (SIPX) with (NS). Functional characteristics were confirmed elemental analysis, thermogravimetric and infrared spectroscopy. This SIPX functionalized (SIPX-NS) incorporated natural rubber (NR) composites used to evaluate the dispersion silica in also interaction between filler. The fi...

Metal xanthates are widely used as single-source precursors for the formation of metal sulfide thin films. In this study, we explore length alkyl ligand an efficient tool to control and nanoporosity zinc The presented approach allows us prepare highly porous films with potential applications in photocatalysis, whereby is significantly enhanced increasing number carbons chain xanthate precursors...

• Cu 2+ -treated pyrite improved fine chalcopyrite flotation recovery as a carrier. CuSO 4 treatment of its hydrophobic interactions with particles. The mineral particles in is limited owing to the low collision probability between and air bubbles. carrier method can enhance particle by attaching fines coarse In this study, an attempt was made improve using Flotation experiments for finely grou...
