Aim of the inquiry: Extraction to multifunction of technology of the enrichment of low-grade phosphorous orc with the use as flotation reagent waste of oil mill. Methods of inquiry:For revealing the feature of phosphorous orc we studied its composition by means of chemical, mineral, phase and spectral analysis. For determination of phosphorus photo colorimetrical and method of besieging in the manner of magnesium ammonium phosphorous orc used. The Chemical composition of orc is defined bu the complexonomctric, permanganatometric, and photocolorimetrical methods. X-ray and phase analysis run for difraktometr DRON-05, spectrums removed on spectrometer UR-20. The results achieved and their novelty: Optimum multifunction of technology of the enrichment low-grade phosphorous orc with the using as flotation reagent waste of oil mill and new flotation reagent "Fomol", permissible getting the standard concoction with the contents of P2O5 27-28% is exhousted. Practical value: On the base of the research and hall-industrial tests multifunctional technology of the enrichment of low-grade phosphorous ore of Dzhcroy-Sardara deposit is exhausted, allowing to raise the contents P2O5 from 14,8% in orc till 26-27% P2O5 in concoction, as well as reduce the calcium module from 2,48 till 1,85. Degree of embed and economic effectivity: Exhausted technology passed frogs hall-industrial test on concentrating equipment OJV "Ingichka experienced-methodical technological expedition". Expected annual economic effect from introduction designed technologies on KPC NMMC will form 17,543 mln. sooms per 100 000 tons annum. Sphere of usage: Mining-metallurgical and chemical industries.
