Improvement of sulphide-oxide copper ores processing through the use of mixed collector systems has surged. the flotation of a natural porphyry copper ore with bornite and malachite was investigated via fundamental work with pure minerals and a bench-scale testing regime..

Flotation Of Mixed Oxide Sulphide Copper

Flotation Of Mixed Oxide Sulphide Copper

Jul 01, bulk flotation experiments with zambian copper-cobalt sulphide ore showed superior flotation performance, with improved kinetics, when using sodium ethyl xanthate (sex) as a collector instead of a blend of alkyl dithiophosphate and thionocarbamate collectors, with copper sulphides floating more rapidly than cobalt sulphides (mainza et al.,.

Flotation Of Mixed Oxide Sulphide Copper

Flotation Of Mixed Oxide Sulphide Copper

Jul 01, three cobalt-bearing oxide minerals are observed in the mixed ore, i.e. heterogenite, kolwezite and cupro-asbolane, while carrollite is the only cobalt-bearing sulphide mineral. a two-stage rougher-scavenger flotation process is used in which sulphides are extracted from the ore.
