FIELD: chemistry. ^ SUBSTANCE: present invention relates to a floatation agent containing a collector composition of hydrocarbons for foam floatation of ore minerals. The floatation agent contains a collector composition of hydrocarbons contains more than 80 wt % isomeric and normal paraffins, less than 1 wt % aromatic compounds, less than 5 ppm sulphur and less than 1 ppm nitrogen, and has density between 0.65 and 0.8 g/cm3 at 15C, and at least one foaming agent. The invention discloses use of the floatation agent, wherein the amount of the paraffin hydrocarbon composition ranges from 50 to 250 g/t. The invention also discloses use of gas oil or kerosene containing said paraffin hydrocarbon composition. The method for foam floatation involves floatation of ore or mud using an effective amount of said collector composition of hydrocarbons. ^ EFFECT: high efficiency of floatation, environmental safety. ^ 15 cl |
