    The invention relates to the enrichment of minerals, and in particular to the method of flotation of oxidized tin
    RUD
    There is a method of flotation of oxidized tin ores, involving the addition of 2-phenylethylene phosphonic acid to the suspension of crushed ore as a collector, control reagents and blowing agents.
    The purpose of the invention is to increase the degree of extraction of tin.
    The method is carried out as follows.
    The tin ore is ground to a particle size of less than 0.1 mm, suspended in a hearth, to which is added to clean the surface. Then, wasp flotation in the presence of a blowing agent using a collector mixture consisting of 2-phenylethylene phosphonic acid and a biolipid extract obtained from the yeast Lodderomyces elongisporus grown on hydrocarbon oil. The ratio of 2-phenylethylene phosphonic acid and biolead extract is 1: (0.25-1.5). It is advisable to use the collector mixture in the form of an aqueous emulsion. Partial application of the biolipid extract in the form of sodium soap contributes to emulsification, and the saponification depth is 35-70%,
    The table presents the data of grinding of tin by fraction 1 p m.
    Using a mixture of 2-phsnylethylene phosphonic acid and biolipid

    the extract increases the size of the particles of the material undergoing flotation, which increases the degree of extraction of tin (table).
    Example 1. A biolipid extract is obtained as a by-product after the extraction purification of the yeast Lodderomyces elongispori s JMET H128, boosted on distillate oil with a boiling point of 237-377 ° C. 1 mm, suspended in water to obtain a suspension with a density of 1.7 kg / l. 250 g / t is added to the slurry to clean the surface of the tin ore. After a partial change of water, the tin contained in the pulp is floated using 200 g / t of collector mixture consisting of 50% 2-phenylethylene phosphonic acid and 50% of the biolipid extract previously saponified to a depth of 70%.
    Biolipid extract has the following composition,%:
    Phosphatides 38.5 Glycerides and free fatty acids19.0
    Biogenic components2, 5, Hydrocarbons 40.0 Octanediol is used as foaming agent. The degree of enrichment is 6.37, and the extraction of tin is 80.2%. When using as a collector only 2-phenylethylene phosphonic acid, the degree of enrichment is 8.37, and the increase in tin is 76.3%.
    Example 2: The method is carried out according to Example 1, but nonylphenol is used as the blowing agent. The degree of enrichment of 7.37, the extraction of tin 83.1%. When using only 2-phenylethylene phosphonic acid as a collector, the same degree of enrichment is achieved, and the extraction of tin is 82.2%.

    Example 5 The method is carried out according to example 4, but the ratio of 2-phenylethylene phosphonic acid and biolipid extract is 1: 1.5. The degree of enrichment is 6.07, the extraction of tin is 78.9%.
    Thus, the proposed method of flotation of oxidized tin ores allows to increase the extraction of tin from the ore.
