METHOD OF OCEANIC FERROMANGANESE CONCRETION REPROCESSING

摘要

FIELD: metallurgy. SUBSTANCE: at the process of leaching at pH 4.5-3.0 sulfur (0.7-2.0 g / 1 g copper) is added to the pulp, and copper sulfide formed is separated by flotation. Sulfur particle size i 0.044-0.300 mm. Leaching involving sulfur addition is carried out at 50-95 C. EFFECT: simplified technology, decreased reagent consumption. 3 cl
