A process for beneficiating a finely ground ore containing sulfide minerals of copper and nickel by selective flotation to produce a copper concentrate and a copper-nickel concentrate comprises pulping the ore with water to form a slurry, conditioning the slurry with an aqueous solution of SO 2 (H 2 SO 3 ) equivalent to from about 2 to about 4.5 pounds of SO 2 per ton of dry ore for a time ...

Chalcopyrite Group. Chalcopyrite-Eskebornite Series. A major ore of copper. Common in sulfide veins and disseminated in igneous rocks. Weathering may lead to the formation of malachite, azurite, brochantite, langite and numerous other secondary copper minerals. A Zn-rich variety is known from Atlantis II Deep (see zincian chalcopyrite). Compare, e.g., UM1991-16-S:CuFeTl, UM1988-17 …

The flotation of pyrite was depressed strongly by SGX while the floatability of chalcopyrite only slightly reduced at the pH range 7–10, and the optimal differential flotation chalcopyrite from pyrite was achieved at weakly alkaline pH range, with SBX as collector.

The flotation results were explained in terms of the decrease in the hydrophobicity of the mineral surfaces due to the adsorption of hydrophilic groups in these organic materials which then prevent bubble-particle adhesion.

The peak A1 corresponds to chalcopyrite oxidation by reaction (7).2 A cyclic voltammogram was drawn to elucidate the redox behavior of chalcopyrite in pH 9.b). (a) Cyclic voltammogram of chalcopyrite …

The flotation of chalcocite, bornite, chalcopyrite, and pyrite has been studied in a microflotation cell in which the potential of a bed of the mineral particles could be controlled electromechanically. The ethylxanthate-induced flotation of each mineral is markedly dependent on electrochemical potential, with the recovery changing from 0 to 100 pct in potential intervals of - 0.2 V.

Preparation of the chalcopyrite ore was designed to produce a flotation feed with the same characteristics as those of the actual flotation feed at the Cyprus Bagdad mill. The ore sample was crushed with laboratory jaw and roll crushers to below 2,000-µm size.

Various collectors were compared in the selective flotation of copper–zinc ore by using isopropyl ethylthionocarbamate (Z-200), buthl xanthate, ammonium dibutyl dithiophosphate, and mercapto benzothiazole (MBT). The latter showed effective selectivity in the flotation of chalcopyrite and marmatite and was selected for a detailed study by using cyclic voltammetry and Tafel.

The processing of complex sulphide ores by the sequential method of flotation requires maximal selectivity. In particular, the entrainment of galena into the chalcopyrite concentrate obtained with a dialkylthionocarbamate-type collector must be minimized.

In this paper, the effect of presence of nano-microbubbles on flotation recovery of chalcopyrite fine particles (-38+5 m m) has been studied. Comparative flotation tests were performed both in the presence and absence of nano-microbubbles (conventional flotation) to evaluate recovery changes of chalcopyrite.
