The total and acid soluble copper assays of the tail from Test D were 0.19% and 0.16% Cu, respectively. This shows that the residual copper found in the tail was mainly associated with copper oxide minerals. The total copper, sulphide copper and oxide copper recoveries of 95.5%, 98.2% and 89.4%, respectively.

The present investigation has studied the respective roles of sodium iso-propyl xanthate (SIPX) sodium di-ethyldithiophosphate (DTP) and alkyl hydroxamate in the flotation of copper sulphide from copper slag. Flotation performances were increased effectively by the combination of collectors.

Flotation of copper oxide minerals: A review. Qicheng Feng, ... Guang Han, in International Journal of Mining Science and Technology, 2022. 1 Introduction. The continuous development of the global economy has resulted in a high demand for copper production and high copper consumption [1,2], and exploitation and effective use of copper oxide mineral resources have …

The increasing complexity of ore deposits, declining ore grades and higher global demand for copper has resulted in increased ore processing by flotation plants around the world. The depletion of highgrade ores, increased demand for metals and separation difficulties associated with low-grade or refractory ores, has resulted in new flotation ...

The distribution of copper sulphides in each test feed by exposure class was calculated by summation of the concentrate and tails data. Distribution of copper sulphides in the sample feeds by exposure class data is presented in Figures 4 through 6. Sample 1 had a low degree of copper sulphide surface exposure, despite being a fresh feed sample.

Approximately 90 % of copper is obtained from sulphide deposits, with chalcopyrite, the most abundant copper-bearing mineral in nature, accounting for nearly half of global copper production [3]. As high-grade copper deposits become increasingly scarce, the processing of low-grade and complex copper ores has gained prominence in the global ...

(Malghan, 1986). Three steps were identified for copper oxides: ad-sorption of sulphide ions with the formation of copper sulphide, sul-phide oxidation, and desorption of oxidised compounds by ion ex-

The gradual decrease of global copper resources is among the most urgent challenges for the mining industry. Sustainable utilization of copper sulphide flotation concentrate from iron oxide copper gold (IOCG) deposits is often constrained by the impurity elements (e.g. U, Th and F) and high levels of gangue minerals (e.g. iron oxide/hematite, U-bearing minerals and fluorite).

Grinding conditions affect the flotation of copper sulphide minerals as changes in the properties of the grinding media and their interactions with the sulphide minerals, and …

Grinding conditions affect the flotation of copper sulphide minerals as changes in the properties of the grinding media and their interactions with the sulphide minerals, and between sulphide minerals themselves, affect the chemical environment in the flotation pulp. Galvanic interactions between steel grinding media and sulphide minerals, and between sulphide …

spectives on depressants vis-à-vis flotation separation of Cu–Fe sulfide minerals at low alkalinity are proposed. Keywords: Cu–Fe sulfide minerals; flotation separation; selective depressants; depression mechanism 1. Introduction Copper (Cu) is an important nonferrous metal and is used as a raw material in industrial production. It is ...

copper sulphide minerals and 93% of carrollite co uld be recovered from mixed oxide sulphide ore at ambient pH in a laboratory batch flotation experiment. Final concentrate grades after the sulphide flotation stage were 12.2% Cu and 0.38% Co [11]. Flotation processes are typically optimized through changes of reagent dosage and flotation

Flotation of Copper Ores . By Donald I. Bleiwas . Open-File Report 2012–1089 . ... Much of the global supply of copper originates from mines that also produce byproduct molybdenum, but for simplicity, a single copper concentrate has been modeled for this study. ... Copper sulfide ores must be concentrated before they can be economically ...

The flotation by surface sulphidisation of the oxidized copper-cobalt-bearing ore from Kimpe (1.97% Cu; 0.66% Co) was studied in order to evaluate its behavior by the analysis of its most ...

Global copper supply is dominated by sulfides, but standalone oxide projects can be attractive at smaller scales. Sulfide Copper Characteristics. Sulfide extraction is more complex, requiring physical separation via froth flotation after fine grinding. This produces a copper concentrate rather than pure cathode copper.

Flotation of sulphidic and oxidic copper minerals is reviewed, with particular reference to previous studies of refractory copper ore flotation.

The role of ore mineralogy on the flotation performance of copper-cobalt sulphides was studied by tracking the changes in mineral properties with time throughout the flotation process.

The global market has announced copper as a modern energy metal and finds its extensive utilization in the construction industry, electrical wiring, power transmission lines, alloying ...

Sulphide ores are the major sources of base metals like Copper, Lead, Zinc, Nickel and Cobalt. Beneficiation of these base metal sulphide minerals is predominantly through the froth flotation …

"Mild oxidation" could lead to enhanced hydrophobicity of the copper sulphide minerals owing to surfaces rich in intrinsically hydrophobic species such as elemental sulphur and polysulphides (Heyes and Trahar, 1977). This constitutes the well-known collectorless flotation phenomenon of copper sulphides such as chalcopyrite.

Lime is used in the metallurgical processing of different copper ore types, ranging from flotation of copper sulphide minerals to leaching of copper oxides by acid lixiviants. The main products from such operations are copper concentrates (containing 25 – …

The mineral composition of copper–cobalt ores is more complex than that of copper sulfides, and it is also difficult to discard tailing efficiently in primary flotation for the fine-grained disseminated of ore. In this work, a mineral liberation analyzer (MLA) was employed to study the characteristics of minerals. As a significant mineralogical characteristic, the liberation …
