In order to investigate the influence of particle size on flotation behavior coal slime, industrial analysis, elementary and composition analysis were carried out slime. The slime is divided into three sizes: −0.5 + 0.25, −0.25 0.074, −0.074 mm, full mm sizes. Through contact angle measurement, wetting heat step-by-step release test hydrophobicity each size; in addition, kinetics different size...

Abstract Pyrite is separated from other minerals mainly by flotation. However, the hydrophilicity of pyrite affected many factors, causing it to easily enter concentrate and consequently reduce quality concentrate. Highly efficient depressants can be selectively adsorbed on surface improve its hydrophilicity, thereby increasing flotation separation efficiency. Understanding fundamental inhibiti...

The article presents one of the new approaches to theoretical assessment collecting ability reagents. efficiency reagents-collectors with different chemical composition used for flotation coking coals was studied. A comparative activity kerosene, mineral oil, thermal gas KETGOL and FLOTEK is given. criteria above coal sludge were specified. correlation established between indicators by reagents...

The development of froth flotation is traced from its earliest-known use through the discoveries leading to the present knowledge of the science. The factors influencing the flotation of non-sulfide and non-metallic minerals are discussed, and the machines used in commercial flotation operations are described. Experimental work on the flotation beneficiation of phosphate rock is presented as an...

The present work investigates the conjugation of flotation and photo-Fenton techniques on oil removal performance from oilfield produced water. The experiments were conducted in a column flotation and annular lamp reactor for induced air flotation and photodegradation steps, respectively. A nonionic surfactant was used as a flotation agent. The flotation experimental data were analyzed in terms...
