    The invention relates to the field of mineral processing and allows for increasing the efficiency of flotation by increasing the dissolution of the collecting agent (PC) in water. A PC consisting of three components is preliminarily introduced into the aqueous pulp: a yew compound, a surfactant, and an alcoholic component containing from 3 to 12 carbon atoms. Their ratio is as follows (wt.%): TI-compound 30-60 j surfactant 20-55; alcohol containing from 3 to 12 carbon atoms 5-30. The thio compound is selected from the series: mercaptans containing from 8 to 18 carbon atoms, polysulfide alkyls containing from 16 to 36 carbon atoms and from 3 to 8 sulfur atoms. As a mercaptan, m. p-dodecyl mercaptan or tertiary dodecyl mercaptan was used. As polysulfide alkyl, polyalkyl sulfides of the formula RS are chosen, (- R, where R, R are the same or different hydrocarbon radicals containing from 1 to 14 carbon atoms, x is an integer from 3 to 5, in particular, tri- or penta disulfides of di-tertiary nonyl or di-tertiary dodecyl. The composition of the PC ensures the formation of a PC microemulsion after its introduction into the mineral pulp. This allows the use of practically water-insoluble thio compounds, 3 3.pf files.

    EXAMPLE 2 Experimental conditions are similar to those of Example 1, but instead of p-dodecyl mercaptan, tertiary dodecyl mercaptan, tertiary dodecyl penta sulphide, tertiary nonyl penta sulphide, and tertiary nonyl trisulfide are used. The best results were obtained using the composition according to the invention (75.8 and
    73.7%, 65.2%, 59.9%).

    EXAMPLE 3 Experimental conditions are similar to those of Example 2, but tertiary dodecyl trisulfide was used as a thio-compound, and the ratio of alcohols: isopropanol — 6.25%, 2-ethylhexanol, 3.35%
    The best results are also obtained with the introduction of the mixture corresponding to the invention (58.1%).
    EXAMPLE 4 Experimental conditions are analogous to example 1, but amyl xanthate sodium potassium is added as a collector in the form of an aqueous solution. Copper recovery was 56.7-80%.
    Xanthate provides a higher recovery of copper, but dramatically reduces the quality of the concentrate from 14.6 to 16.4% (examples 3-6) to 10.4%, i.e. practically 50% of the required metal content in the flotation product
    Example5. 0.5 kg of lead ore was crushed to a particle size of 90% of the class of 100 μm and floated at pH 10 for 15 minutes. The flow rate of the blowing agent was 310 kg / kg. As collectors, the composition was introduced corresponding to the variant a of example 1 of the following composition.%:

    p-Dodecyl mercaptan 55 NONILPhenolheptaoxyethylenene 33.75 Methylisobutylcarbinol 4.5 Ethyl 2-hexanol 6.75. In addition, a collector was used, containing:%
    p-Dodecyl mercaptan 90 Nonylphenoldecoxy-ethylene10
    The extraction of lead and zinc was 91.5 and 98.2% in the case of the composition according to the invention and 68.5 and 54.3% in the case of using the known emulsion collector + surfactant.
    Limer 6. According to example 1, a series of experiments was carried out with a collector consumption of 35-10 kg / kg for various 0 ratios of the components of the mixture. From the data obtained it can be seen that when the surfactant content is less than 20% or more than 54%, the yield of copper decreases rapidly.
    Example 7. Various polysulfide and mercaptans were tested as thiosoate;
    Mercaptans containing less than 8 carbon atoms, Provide the same results as known emulsions. Mercaptans containing more than 18 carbon atoms reduce the yield of copper. The best are mercaptans containing 8-18 carbon atoms.
    Polysulfide alkyls are less than Cg, i.e. containing only 16 carbon atoms, do not provide an advantage over the known method. Outside C, d, copper output is sharply reduced. Optimal are polysulfides C, | j-Cjg (in total), containing 3-8 sulfur atoms.
    EXAMPLE 8 The conditions of the experiment are similar to those of example 2, but alcohols with different numbers of carbon atoms were used as the alcohol. Best results were obtained using alcohols.
    WITH..
    Thus, the use of the proposed method allows to increase the extraction and copper content by 25.8-30% and 3-5%, the extraction of zinc by 34.9%, lead by 35.2%, i.e. improve flotation efficiency.
