A method of processing material serosorting
According to experimental results (experiments 1-3, 6-7) additive to cereulide material mixture svezheosazhdennoi calcium sulfate and elemental sulfur allows you to select 66,1-87,4% of elemental sulfur in the class plus 210 μm, favorable for the process of sulfuric melting, and get a high quality sulfur and sulfide concentrates, regardless of the type of calcium reagent-hydrophilization: sulphur concentrates contain 80,6 and 88.5% of elemental sulfur, sulfide and 2.1% to 3.8%. While removing elemental sulphur in sulphur concentrate is to 91.6-97,6%.The comparison of the results of the experiments 6,7 with the results of experiments 1-3 table shows that the mixture svezheosazhdennoi calcium sulfate and elemental sulfur effectively work as entered in the composition obtained from the technical sulfur). Given the specificity of the technology of production and processing serosurvey materials, the option of introducing seocalcitol mixture comprising sulfur concentrate seems to be the most rational. 1. A METHOD of PROCESSING SEROSORTING MATERIAL obtained after acid autoclave-oxidative leaching of sulfide raw materials, including water treatment pulp material calcium reagent-hydrophilization in the presence of organic surfactants at a temperature above the melting point of elemental sulfur, cooling the slurry and subsequent flotation of obtaining sulfur and sulfide concentrates, characterized in that the treatment is carried out with addition of a mixture containing svezheosazhdennoi calcium sulfate and elemental sulfur at a mass ratio of calcium sulfate and elemental sulfur 1 : (8 - 100), in quantities of 1 to 25% by weight serosorting material.2. The method according to p. 1, characterized in that the mixture obtained using sulfur concentrate.
SUBSTANCE: method for separation of the elemental sulphur and sulphide concentrate from the intermediate products of the sulphide concentrates hydrometallurgy processing includes sulphur-sulphide flotation of the intermediate original pulp in order to separate the sulphur and sulphides from intermediate oxide components with forming of the sulphur-sulphide concentrate. Then the autoclave disintegration of the sulphur-sulphide concentrate pulp is carried out in the presence of reagent - sulphide hydrophilisator and at the temperature higher than melting point of the elemental sulphur. After that the sulphur flotation is carried out in order to separate the disintegrated pulp into sulphur and sulphide concentrates. Before the sulphur-sulphide and sulphur flotations the pulp undergoes the additive agitation with the reagents, the disintegration is carried out at the temperature 140-150°C.
EFFECT: effective separation of the sulphur and sulphide concentrates.
