METHOD FOR SEPARATION OF ELEMENTAL SULPHUR AND SULPHIDE CONCENTRATE FROM INTERMEDIATE PRODUCTS OF SULPHIDE CONCENTRATES HYDROMETALLURGY PROCESSING |
摘要 |
FIELD: chemistry. ^ 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 140-150C. ^ EFFECT: effective separation of the sulphur and sulphide concentrates. ^ 5 cl, 3 dwg, 1 tbl |
