METHOD OF COPPER-MOLYBDENUM ORES SEPARATION Russian patent published in 2013 - IPC C22B34/30 C22B15/00 B03D1/00

Abstract RU 2481410 C1

FIELD: metallurgy.

SUBSTANCE: proposed method comprises ore pretreatment, bulk flotation in alkaline medium at pH 11-12 to obtain copper-molybdenum concentrate. Bulk copper-molybdenum concentrate is subjected to treatment by bacteria Pseudomonas Japonica with titre of 6·10⁷ kl/ml for 2-5 min. Then, selective flotation is performed to separate molybdenum and copper into foam product and flotation tail, respectively.

EFFECT: higher efficiency, intensified process.
