METHOD FOR EXTRACTING USEFUL COMPONENTS BY LEACHING

摘要

FIELD: hydrometallurgy, namely processes for extracting useful components at using continuous autoclave oxidation leaching of metals. SUBSTANCE: method comprises steps of preparing ore material by disintegration; continuously making initial pulp; leaching pulp in autoclave under increased oxygen pressure at forced displacement of pulp volume; settling useful components. Novelty is preparation of initial pulp at continuously feeding oxygen-saturated water under pressure exceeding pressure in autoclave onto supplied prepared ore material. Water is guided onto continuously fed prepared ore material in direction of pulp displacement at leaching in autoclave under pressure exceeding by 1.5 - 2 times pressure in autoclave. EFFECT: enhanced efficiency. 3 cl, 1 dwg
