duce a marketable fraction enriched in cobalt and nickel. Ferric chloride leaching of various chalcopyrite (copper) concentrates has yielded residues containing from 10.2 to 16.2 pct Ni and 8.3 to 11.4 pct Co with recoveries of approximately 79 pct. In another approach, laboratory froth-flotation tests

associated to pyrite. The froth flotation and behaviors of chalcocite and carrolite were investigated through many 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
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 ...

The major cobalt source in the ore is the mineral siegenite. Separation and concentration of siegenite by froth flotation is complicated by the mineralogy of the ore. The siegenite is often present as an intimate replacement intergrowth with chalcopyrite (fig. 1), sphalerite, galena (fig. 2), and the iron sulfides, pyrite and marcasite.
Sulphidisation followed by flotation is the preferred beneficiation technique for oxidised copper-cobalt ores. • The integration of CPS systems into the flotation circuits can help minimise reagent overconsumption. • Application of selective flotation can help a concentrator to produce separate oxide and sulphide concentrates.
Mineralogical analyses showed the cobalt present as a distinct mineral phase, predominately siegenite, amenable to a physical separation method such as froth flota tion. Flotation was chosen for recovery because of easy adaptation by the mills. Unit processes of grinding, conditioning, and flotation were studied individually and in con
The froth flotation and behaviors of were conducted and-have shown that at pH (about 4), the chalcocite and carrolite were investigated through many flotation tests in order to recovery copper and cobalt.
Froth flotation is particularly effective in recovering cobalt, nickel and copper minerals from above ground ore stocks and underground ores. The MMPP is designed to handle 300-360 tons per day of feed and can produce 1000-1500 tons per month of feedstock for the Hydrometallurgy Refining Process.
