COPPER-NICKEL ORE ENRICHMENT PROCESS Russian patent published in 1999 - IPC

Abstract RU 2133153 C1

FIELD: mining industry. SUBSTANCE: invention, in particular, relates to concentrating copper- nickel sulfide ores and can be used for concentrating other sulfide ores. Process consists in crushing ore, screening crushed ore to isolate ore with particle size below 100 mm, separating the latter into sulfide and rock fractions by screening it through screen with mesh size 20 to 40 mm, additionally crushing rock fraction into sulfide fraction, mixing the two fractions before or after crushing, aerating and selectively floating resultant pulp to isolate copper, nickel, and pyrrotine concentrates and reject tails. EFFECT: simplified process. 3 cl, 3 dwg, 1 tbl
