Assessment of collecting activity of physically sorbed reagents on the example of easily floatable coking coal sludge
نویسندگان
چکیده
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 their physical parameters. It shown that rate spreading over water surface can characterize Based on dependence a reagent its along “gas – liquid” interface pressure, main determining structure molecules an effective collector be determined. concept function performed physically sorbed in elementary act criterion beneficiation are proposed. flotation, addition hydrophobizing extracted particles, should reduce induction time remove kinetic constraint formation aggregate.

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
