    The invention relates to non-ferrous metallurgy, in particular, to the technology of processing raw materials by sulphating roasting.
    The aim of the invention is to increase the recovery of non-ferrous metals into solution.
    The natural raw material consists of sulphides or metal oxides, which are easily converted to the sulphide or oxide form. Ferrites of various metals can also be successfully processed. In addition, the method can be used to process some silicates, carbonates and phosphates either alone or in combination with oxidation or sulphation.
    Clause 1. In order to select the appropriate operating conditions for the different starting materials, a series of experiments are carried out with copper concentrate containing copper in whole chalcopyrite. The concentrate contains 28.0% Cu and 3.8% Zn. The experiment was carried out with Na - HjO- rozit, which contains 0.8 grams of Na molecules or with Na-K-Rozit, which contains 0.43 grams of Na molecules, and 37 grams of K molecules (per gram-mo - a rosit compound compound) or with a synthetic compound NaFe (S04) 2 as an additive contributing to the formation of sulfate. The experiments were carried out in a conventional laboratory furnace in open crucibles in an atmosphere of air.
    The results are shown in Table. one.
    Example 2. The con is used according to example 1 with the exception of the content 80, which is increased, and the content 0 is reduced by closing the crucibles with lids.
    The results are shown in Table. 2
    An experiment was also conducted in which 200 mg of the concentrate, together with 300 mg of NaFe (S04) 2, were placed in an autoclave. After 25 minutes, the material was still mostly in the form of sulfide. Therefore, when sulfatization is carried out according to the proposed method, one of the basic requirements is a sufficient amount of oxygen.
    Example 3. The treatment of examples 1 and 2 is carried out with several

    Co concentrates containing 18-20 gram molecules per percentage of Co. The results are shown in Table. 3
    Example 4. The treatment according to examples I and 2 is carried out with and CoO in the usual atmosphere of air using compound (S04) i, which is included in the system -Fe (S04) g. The results are shown in Table. four.
    Sulfation can be carried out in the melt without the use of any sulfur trioxide from the atmosphere.
    Example 5. A melt is obtained from K-N and Cu sulphates with a molecular ratio of 1: 1: 1. 200 mg of FcjOg is added to the melt and the mixture is treated for 1 hour. The content of water-soluble iron, which is used to form the sulfate, is 0.6 mg. Under the conditions considered, FsjOj only dissolves slightly in the melt.
    Example 6. The treatment of examples 1, 2 and 5 was carried out on the slag heap of the slag concentration plant used to melt zinc. The chemical composition of the slag,%: Cu 0.45 j Zn 3.5; Mg 1.3 and Ca 0.82. The compounds are mainly represented by silicates. The treatment is carried out at 630 ° C in an atmosphere of air; the reaction time is 1 h. The ratio of silicate and sulfate in a 1: 1 mixture.
    The results are shown in Table. five.
    The proposed method is also applicable to siliceous slag. This material is difficult to process economically in other ways. The method can also be applied to the treatment of the starting material with a low metal content.
    Example 7. A similar treatment (examples 1-6) is carried out on a mixture of - FeS04 with a molar ratio of 1: 1 and copper concentrate from example 1 at a temperature and reaction time of 1 hour. The ratio of copper concentrate to sulfate is 200 mg / 400 mg. The yield of water-soluble copper 93%.
