1988-8-1 The various copper-cobalt ores mined by Gecamines, together with typical plant applications and results, are briefly described. Intensive laboratory investigations have been undertaken in recent years to improve the metallurgical performances of the various concentrators. As a result of these tests, it was shown that the flotation of the siliceous oxide ores could be improved by increasing the ...

2020-4-16 Abstract— Copper and cobalt are two major metals used in industry. They play a role in widely many domains like that electricity, chemistry and electrochemistry. They are contained into several minerals like chalcopyrite, carrolite, chalcocite, etc. associated to pyrite. The froth flotation and behaviors of

2019-7-1 Portable X-Ray Fluorescence (pXRF) was used to analyse the copper and cobalt content of the individual flotation products. The device used was the Delta Premium Handheld XRF Analyser (Olympus, United Kingdom) in Geochemistry mode. Detection limits for copper and cobalt are 20 PPM for cobalt and 5 PPM for copper (Innov-X, 2010).

Previous Bureau of Mines research to recover cobalt from the copper concentrates has included both hydrometal lurgical and flotation studies. Hydrometallurgical schemes have utilized a ferric chloride solvent in an oxidative leach to treat the copper concentrate and leave the cobalt in a cobalt-enriched residue. Although successful, this scheme

2016-6-7 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.

2018-8-20 0.70% copper, 0.50% cobalt and 21.98% sulfur. The K-Amyl xanthate and Dowfroth 250 used in flotation were taken from the Ergani Copper Mining Co in Turkey. The chemicals used in these studies such as 96% (w/v) H2SO4, 37% (w/v) HCl, 65% (w/v) HNO3, FeS and KClO3 were purchased from Merck. The sample crushing was broken in a crusher belonging to

Copper-Cobalt ores. Various cobalt bearing minerals have economic significance including cobaltite (CoAsS). carrollite (Cu (Co.Ni)2S4), and linnaeite (Co3S4). These are often associated with copper minerals and pyrite and pyrrhotite iron sulphides. Two different flotation separation strategies are used.
