    • 专利摘要:
    A process for separating molybdenite from copper sulphide and other metal sulphide minerals with which it is associated in a metallurgical concentrate through use of a copper sulphide depressant which is a compound having at least one nitrogen atom, at least one thio group and at least one hydrophilic group. Some examples are 2-thiouracil, pseudothio-hydantoin, and 2-imino-4-oxo-5-thiazolidineacetic acid.

    The method is carried out as follows.
    Copper-molybdenum product, which is a rough concentrate of collective flotation or concentrate from the cleaning of the rough concentrate, pulping to a content of 15-50%
    solid By adding an alkaline agent: lime, sodium hydroxide, or another, the pH of the pulp is adjusted to 8-12. Then one of the listed compounds is introduced into the pulp and conditioned with stirring for 1–20 minutes.
    The consumption of modifiers is 0.045-0.45 kg per ton of concentrate. Into the prepared pulp is injected
    collector: hydrocarbon oil and
    blowing agent: 4-methyl-2-pentanol and float molybdenite.
    The consumption of the collector, for example kerosene, with the addition of fuel oil - 0.092, 27 kg / t, foaming agent - 0.14 kg / t. Flotation time 2-10 min.
    Modifiers can be introduced into the pulp in the form of solid particles, but it is preferable to use them in the form of aqueous solutions in which alkali or acid can be added to increase the solubility of the compounds.
    Example 1. Modifiers tested in the flotation of a rough concentrate containing 26% copper and 2.7% molybdenum. The pH of the suspension was adjusted by adding lime and adjusted to 10. Conditioning with modifiers was carried out for 20 minutes. Collector: kerosene - 0.9 kg / t.
    As a result of the process installed.
    Extraction of molybdenum in concentrate with the use of acidic sulfurous sodium (known modifier) was 89%. Its consumption at the same time 45, 4 kg / t.
    The use of these modifiers, depending on their particular type, allows for the extraction of 8492% molybdenum. Their required consumption was 6.8-13.6 kg / t, i.e. with almost identical process indicators, it was more than 3 times lower
    Example 2. Floated concentrate with a copper content of 10%, moliden 0.4%. The use of acidic sulphurous sodium allows to extract 84-87% of molybdenum, these compounds - 75-89% with a reduction in consumption of 10-40 times.
    Example 3. The concentrate, flotation flotation, contained 27% copper and 1.7% molybdenum. The natural pH of the suspension was 10, so the alkaline agent was not added.
    The flotation results show that acidic sodium sulphide contributes to recovery of up to 91% in the concentrate. Using the recommended modifiers allows you to extract 80-94% molybdenum while reducing consumption by 3 times.
    - As such, the consumption of these modifiers is significantly lower than the known. In this case, a number of them, namely, thiobarbituric acid, 2-t iouracid, 2-methyl-2-thiouracil, thioorotic acid, thiogidantoin, allow to increase the recovery of molybdenum in the concentrate by 1-3%. This is the main advantage of this invention.
