1. Способ флотации пентландита из полиметаллических пирротинсодержащих материалов, включающий предварительную обработку пульпы материала в известковой среде солью дитиокарбаминовой кислоты, кондиционирование с сульфгидрильным собирателем и вспенивателем и постадийное флотационное выделение пентландита в пенные продукты при непрерывном аэрировании пульпы кислородосодержащим газом, отличающийся тем, что выделение пентландита на первой стадии ведут в течение 24-32 мин, а аэрирование пульпы кислородосодержащим газом осуществляют при массовом соотношении элементного кислорода, щелочной соли дитиокарбаминовой кислоты и пирротина 1: (0,02-0,11) : (140-215).1. A method of flotation of pentlandite from polymetallic pyrrhotite-containing materials, including pretreating the pulp of the material in a lime medium with a dithiocarbamic acid salt, conditioning with a sulfhydryl collector and blowing agent, and stepwise flotation of pentlandite into foam products with continuous aeration of the pulp with oxygen-containing gas, which the first stage is carried out for 24-32 minutes, and pulp aeration with oxygen-containing gas is carried out at asses ratio of elemental oxygen, alkali salts of dithiocarbamic acids and pyrrhotite 1: (0,02-0,11) (140-215). 2. Способ по п. 1, отличающийся тем, что в качестве кислородосодержащего газа используют смесь, содержащую 15-45 об. % элементного кислорода и инертные к данной системе газы. 2. The method according to p. 1, characterized in that as an oxygen-containing gas using a mixture containing 15-45 vol. % elemental oxygen and gases inert to this system. 3. Способ по пп. 1 и 2, отличающийся тем, что в качестве кислородосодержащего газа используют абгаз процесса автоклавно-окислительного кислородного выщелачивания пирротиновых материалов. 3. The method according to PP. 1 and 2, characterized in that as the oxygen-containing gas use the exhaust gas of the process of autoclave-oxidative oxygen leaching of pyrrhotite materials.
