In this work, the effect of copper sulphate on the flotation of Mt Keith pentlandite ores was studied. As Mt Keith operates separate size flotation circuits, slime (−8 μm), fine (−25 μm) and c...
The effect of degree of liberation on copper recovery from ...
Copper recovery in concentrates at pH 12 was slightly less, but copper grades were much higher. The effect of grinding was higher at pH 12, especially in terms of copper grades in concentrates, which declined with the increase of grinding time. Ore microscopy tests were done on the concentrates with 55 and 75% of grain size <74 μm at pH 10 and 12.

EFFECT OF GRINDING CHEMISTRY ON THE SULPHIDISATION .
The recovery of copper by sulphidisation and flotation from a mixed ore has been studied in detail in this thesis. Particular focus was given to the effect of pulp chemistry on the sulphidisation mechanism and subsequent flotation response of oxidised sulphide minerals, both of which are not prevalent in the literature.
Leaching of Copper Sulphides
copper sulphide leaching options as alternatives to the more conventional pyrometallurgical processing route of copper sulphides. Three copper sulphide leaching and refining processes are discussed: total pressure oxidation, ferric sulphate leaching and copper chloride leaching. The effect of mineralogy

Influence of Ferric and Ferrous Iron on Chemical and ...
The effects of ferrous and ferric iron as well as redox potential on copper and iron extraction from the copper flotation concentrate of Sarcheshmeh, Kerman, Iran, were evaluated using shake flask leaching examinations. Experiments were carried out in the presence and absence of a mixed culture of moderately thermophile microorganisms at 50C.
Cotreatment of flotation waste, neutralization sludge ...
· Flotation waste of copper slag (FWCS), neutralization sludge (NS), and arseniccontaining gypsum sludge (GS), both of which are difficult to dispose of, are major solid wastes produced by the copper smelting.

In this paper, the influence of Ca2+ on the flotation of a skarn type molybdenum ore and pure molybdenite mineral at pH 8 was studied using diesel as the collector. It was found that Ca2+ had little effect on molybdenum flotation at low concentrations. By further increasing Ca2+ concentration, the floatability of molybdenite—especially from the fine size fractions—was .
Optimization of Chalcopyrite Froth Flotation Process by ...
In this work, we study the froth flotation process of chalcopyrite, with emphasis on the influence of the presence of sludges and clays into the pulp during flotation. For this purpose, the chalcopyrite was mechanically prepared (crushing and grinding), the material was classified (between mesh 100 and 120 and the particle sizes were measured).
Study of Flotation Parameters for Copper Recovery from ...
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.
Multidimensional Optimization of the Copper Flotation in a ...
Three factors were measured in the flotation process of copper ore: the copper grade in a concentrate (β), the copper grade in tailings (ϑ), and the recovery of copper in a concentrate (ε). The experiment was conducted by means of a Jameson cell. The factors influencing the quality of the process were the particle size (d), the flotation time (t), the type of collector (k), and the .

In this study, three lignosulfonatebased biopolymers, DP1775, DP1777 and DP1778 with different compositions were examined as dispersants in copper flotation in the presence of kaolinite. While rheological measurements indied that these biopolymers dispersed the kaolinite aggregates, flotation results revealed that the three biopolymers increased the copper recovery, with a .
