cobalt recovery by flotation

flotation tests in order to recovery copper and cobalt. This paper investigates the effect of potassium amyl xanthate (PAX) and sodium dibutyl dithiophosphate (DANA) performance on both copper and cobalt recovery in single roughing flotation. The effect of pH on the flotation is proposed. Some parameters were

The ancient flotation tailings from Lefke, Cyprus, have a potential for non-ferrous metals such as cobalt and copper from more than 9.5 million tons of reserves containing 0.38% Cu, 0.032% Co, and 22.6% Fe. Recovery of cobalt and copper from these tailings can provide great benefits from economic and environmental perspectives

A hydrometallurgical process for the recovery of nickel and cobalt values from a sulfidic flotation concentrate. The process involves forming a slurry of the sulfidic flotation concentrate in an acid solution, and subjecting the slurried flotation concentrate to a chlorine leach at atmospheric pressure followed by an oxidative pressure leach

That means that the copper-bearing particles are initially recovered, followed by carrollite in later stages of the flotation process. For cobalt, the maximum final grade was observed for sample S9 with 13.0% Co and a cobalt recovery of 66.5% while the highest final recovery was observed for sample S8 with 74.4% cobalt recovery and a final

excellent cobalt-nickel separation primary leach liquor by Cyanex 272. However, manganese extraction from the leach liquor along with cobalt could not be avoided, thus increasing the cost of the process. For sulphide ores, there is another alternative; if the ore can be concentrated by flotation, matte smelting is used instead of leaching

Mineralogical analyses showed the cobalt present as a distinct mineral phase, predominately siegenite, amenable to a physical separation method such as froth flotation. Flotation was chosen for recovery because of easy adaptation by the mills

The real cobalt recovery breakthrough comes from flash flotation of the whole mill discharge rather than the more usual flash flotation of cyclone underflow. Flash flotation tailings are ground to -38 microns and are floated under normal flotation conditions with only the scavenger concentrates being reground to 20 microns

Dec 01, 2013 The present research aims at recovering copper and cobalt through reprocessing of tailings from flotation of oxidised ores of copper and cobalt achieved at the Kambove Concentrator (DRC). It focuses on the determination of the reagents’ dosage that enables obtaining the highest recovery of copper (44.80%) and cobalt (88.30%) through flotation of the studied tailings

Cobalt minerals are generally recovered as by-products during the extraction of zinc, copper, nickel,silver etc. Flotation of cobalt sulRde ores can be bestachieved at acidic pH (&4) with xanthate collectorsand at pH of about 7.5 for oxide ores with nitroso-naphthol chelating reagents, while their mixture isrecommended for oxidized sulRde ores
