Obogashchenie Rud

As is known, one of the mosteffective ways to increase flotation results is development and application of new selective reagents. This line of research isdiscussed in several papers of the current issue of the magazine.

By means of including a regrinding operation and additional application of apolar reagent, based on oil anddiesel fuel, in the Shalkiya deposit (Kazakhstan)finely disseminated ore processing flow sheet, recoveries of lead and zinc in respective concentrates were increased, and concentrates’ grades were also improved (the paper by L. V. Semushkina, et al.).

Application of the new “PS” reagent in the Sayakskoye deposit (Kazakhstan)copper ore flotation permitted to increase copper recovery into concentrate by 0.87 %, and concentrate grade – by 0.4 %, if compared with the results, achieved with application of a conventional flotation reagent – butyl xanthate (the paper by N. K. Omarova, R. T. Sherembaeva, et al.).

The studies performed by V. I. Ryaboy, et alias, established the effect ofsurface activity atliquid-gas interface and hydrophobizationability of dialkyldithiophosphates class reagents-collectors upon their flotation activity. It is shown, that maximum recovery of sulfides is achieved with high hydrophobizationability and surface activity of reagents, and selectivity – with low hydrophobizationability and high or low surface activity, depending on the type of mineral selection.

With regard to otherlines of research, presented in the current issue of the magazine, application of gravity technologies for beneficiation of the noble-metals-bearing ores from the deposits of theRussian North East may be noted (the paper by N. K. Algebraistova, et al.). The results of different gravity concentration apparatuses comparative testing, including centrifugal jigging machine “Kelsey”, are of interest, particularly, that theliterature reports on its operation arecontradictory.

Prospects of an integrated approach to the Zabaikalsky MCC Zavitinskoyedeposit dumps utilization are revealed owing to the results of their geological-technological survey, performed with a view to determine practical ways for production of lithium from the man-caused wastes, to satisfy the needs of electronic, electrotechnics andnuclear power industry(the paper by Yu. V. Azarova, et al.).
