Concentration of oxide copper ores by flotation separation |
| abstract |
Oxide copper ores in subdivided form may be concentrated in a flotation separation process by slurrying said ores in an aqueous solution of a flotation reagent followed by generating gas bubbles in the slurry to float the oxide copper and recovering the concentrated oxide copper from the surface of the slurry, wherein the floatation reagent is II. condensation reaction products of A. polybasic amines of the structure H2N(CH2CH2NH)nH, and B. organic halides of the structure R2Y |
