Xinhai separates two useful minerals that with similar floatability into the mixed concentrate, and then floats each concentrate. That is, copper sulphide and lead ore with similar floatability are selected as mixed concentrate, and copper and lead is separated. Then the tailings were reactivated to separate the zinc concentrate. Application
Fine copper minerals have a low rate of flotation, which may result in losses in recovery. Unlike porphyry copper ore, where the reagent schemes are similar for most operations, the reagent schemes used for the treatment of sulfide copper ores are much more diverse and are designed to cope with specific problems associated with processing the ore.
floatability of new ores. The full methodology is labelled the floatability index test procedure (JKFIT). This paper outlines the JKFIT procedure and the results of applying this methodology to pilot plant data from a copper ore. JKFIT was applied to two different feed sizes (namely a P 80 of 180 microns and 212 microns) of this copper ore.
The largest source of copper is from porphyry ore deposits in which one or a combination of the aforementioned minerals occurs. A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1-xS).
Sep 16, 2018· The natural floatability is good, so flotation is the main method of purifying the copper ore. According to he processing order of the useful mineral, the copper ore process mineral can be divided into precedence flotation, equivalent flotation, mixed flotation and partial flotation.

It was determined that gold and silver could not be reached with satisfactory yields by ...
A Review of the Flotation of Copper Minerals . Font Size. ... These oxidised copper minerals are found in weathered regions of most copper sulphide ore bodies The overlaying oxidic ore is usually stockpiled after it is removed from the sulphide lode and left unprocessed as the sulphide ore is simpler to recover by conventional flotation ...
There is a large storage of copper ore in China and How is copper mined is one of the most important questions when mining copper. Most of the deposit has oxidation zone and some become to copper oxide. The floatability of copper oxide is lower than the sulfide and has a bad grade, high oxidation rate, easy to slime, is difficult to being floated.
Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability.
Beneficiation of Egyptian Abu-Swayel copper ore by flotation 123 RESULTS AND DISCUSSION It is worth to mention that all tests were carried out at 200 g in one dm 3 i.e. at 20% solid/liquid ratio by wt., 250 mg/dm 3 pine oil as a frother and at1000 rpm impeller speed.
Factors affecting the flotation recovery of molybdenite from porphyry copper ores. / Raghavan, Srini; Hsu, Land L. In: International Journal of Mineral Processing, Vol. 12, No. 1-3, 1984, p. 145-162. Research output: Contribution to journal › Article
Characteristics of copper lead zinc sulfide ore is many kinds, useful mineral dissemination fine size, and dense symbiosis; copper sulfide minerals and galena floatability is very similar; sphalerite, pyrite and pyrrhotite easily by copper iron in secondary copper minerals dissolution activation; even the same kind of minerals are often due to ...

copper is also found. Generally the run-of-mine copper ores contain low level of copper and for economic smelting ores are beneficiated to upgrade their copper content. Basically sulphides are beneficiated by froth flotation technique using standard reagent like xanthate for flotation of copper sulphide minerals. The recovery of copper and the ...
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 NON-REFEREED PAPER MARCH 2005 201 Figure 1—The final cumulative copper recovery vs. collector dosage obtained with C2-X, di-C2-DTP and di-C2-DTC in the flotation of the Okiep copper ore
(2) hematite floatability. Hematite floatability better, easily fatty acids flotation collector, therefore, can be used to suppress positive flotation process flotation iron ore gangue minerals can also be used to suppress the iron ore gangue flotation reverse flotation process, but its anti-flotation performance slightly worse than magnetite .

May 30, 2016· Introduction. Different sulphide ores respond differently in the prospect of copper activation to thiols for froth flotation. With the BCL Selebi-Phikwe ore body, pentlandite–pyrrhotite–chalcopyrite co-occur and there is the constraint of fine pentlandite dissemination in the pyrrhotite, so that liberation is limited.

The natural floatability of molybdenite is attributed to its crystal structure. … according to the molybdenum content in the copper concentrate.
In this work, ores containing different types and quantities of aluminosilicate minerals, as well as copper sulfides (i.e., chalcopyrite and chalcocite), were examined in the laboratory to determine how aluminosilicate minerals affect the floatability of copper and to find ways to …
In the case of copper ores (mostly hydrophilic particles) these phenomena are different and the effect of sea water (at alkaline pH range) becomes clearly visible only at high solids content (above 30%). These conditions have been further studied and the results are given in Fig. 3, Fig. 5.
The objective of this study was to investigate the floatability of a complex Kansanshi mixed copper ore comprising sulphide and oxide minerals with a view to achieving an optimal flotation performance in the treatment of the Kansanshi ore body.

Mărăcineanu2 and V.Ciocani1 Flotácia medenej rudy z Roşia Poieni v kolóne s prídavkom nepolárneho oleja The most important natural resource of copper in Romania is the ore deposit of Roşia Poieni.
Copper sulfide ore has good inherent floatability, so flotation process is a mature method used for copper sulfide ore separation. In recent years, with the continuous development of copper sulphide flotation technology, many scholars also proposed a series of new principles of mineral processing, such as "collect early, loss early" and "more crushing and less grinding".
The copper recovery (85.9%) and copper grade (6.7%) of a rougher concentrate obtained using humic acids as main collector for the flotation of a copper sulphide ore from Chile, were very similar to those of a copper concentrate produced by froth flotation under the same conditions with a xanthate type commercial collector.
the similar floatability of copper and zinc minerals. This is especially true when oxidation has caused dissolution of some of the copper, which activates the zinc. Selective flotation in three steps was an early practice on lead-zinc-copper ores.
