copper sulphides, difference in their activity and size create the considerable problems in implementation of selective flotation, obtaining conditional copper and zinc concentrates. Despite several of studies that have been done related to this issue, effective selective flotation of tennantite ores is still the subject to investigation.
From past reviews, the recovery of copper from sulphide mineral using xanthate and pine oil is relatively easy, but mixed oxidesulphide minerals do not respond to traditional sulphide collector. There is no common reagent to recover copper from both oxide and sulphide mineral, which is a great challenge in flotation of both the minerals simultaneously.
Flotation of a copper sulphide ore from Okiep using thiol collectors and their mixtures The Journal of The South African Institute of Mining and Metallurgy VOLUME 105 NONREFEREED PAPER MARCH 2005 201 Figure 1—The final cumulative copper recovery vs. collector dosage obtained with C2X, diC2DTP and diC2DTC in the flotation of the Okiep copper ore

FLOTATION OF COPPER OXIDE MINERALS USING ETHYLENE PHOSPHATE AS ACTIVATORS . By Yang Xiaofeng, Liu Quanjun and Deng Rongdong. Abstract. Abstract. Studying on difficulty of copper oxide`s flotation, the activation of new pharmaceutical KLY refractory copper oxide ore achieves better test results than the other activator.
Effective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics. Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance.
Flotation of nonsulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching. In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated ...
The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral. However this is not the same as the percentage of copper in the ore as that also contains unwanted silies and other minerals, called gangue, that will have to .
laboratory scale batch flotation tests of two sulphide ores at two grinds (80% passing 150 µm, 80% passing 212 µm). Copper mineralisation at Kansanshi occurs as both veinhosted mineralisation, and to a lesser extent sedimenthosted mineralisation. Later brecciahosted and supergene
Oxide copper ore, mixed oxidesulphide ores and lowgrade copper sulphide ore, which, for economic reasons, cannot be enriched by flotation, may be processed by leaching methods. Agents for leaching copper can be acid, base, or salt solutions. Of all of these agents ...
ores. Oxide ores are relatively less amenable to froth flotation and require a judicious choice of reagents for the recovery of metals to be optimised. Laboratory batch flotation tests were conducted to determine the effect of two types of gasoilrinkalore mixtures on the flotation response of a copper cobalt oxide ore sample. The head
About the author. Qicheng Feng is a lecturer at Kunming University of Science and Technology, China. He received his PhD from Kunming University of Science and Technology in 2016 and conducts research on the sulfidization flotation of copper, lead and zinc oxide minerals, and mineral interface evolution of unavoidable components in pulp solutions.
Copper sulphide ores Flotation collectors From previous ﬂotation investigations of mixed copper oxide and sulphide minerals using xanthate and Mineral processing hydroxamate collectors it was hard to distinguish the impact of the alkyl hydroxamate collector on sul Alkyl hydroxamates phide recovery as the sulphide and oxide minerals occurred naturally together.
Copper Oxide Ore Froth Flotation Concentration Plant Overview Copper Ore Flotation Processing Plant is mainly composed of jaw crusher, ball mill, spiral classifier, magnetic separator, flotation machine, ore concentrator and dryer machine combining with ore feeder, bucket elevator and belt conveyor which formed a complete ore beneficiation production line.
xanthate flotation of sulphides and acid leaching of soluble oxide copper. The mixed (transitional) sulphide/oxide ores were stockpiled in the absence of an economic processing route due to their poor flotation response and high gangue acid consumption. Since June 2009, these mixed ores have been treated by flotation using
