Flotation Of Mixed Copper Ore

Copper Flotation - Mineral Processing & Metallurgy

A Copper Flotation Flowsheet Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation.

Treatment of Mixed Sulfide Oxide Ores of Copper

Treatment of Mixed Sulfide Oxide Ores of Copper. The large porphyry mines, with a total copper content of from 1.3 to 2.0 per cent., send to their mills ore with an oxide content of from 0.2 to 0.4 per cent. While the recoveries of the sulfide minerals are considered satisfactory, using modern flotation …

Copper Flotation - Elmhurst College

The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH, pine oil (yes, it comes from trees -- a by-product of stone mills) to make bubbles, an alcohol to strengthen the bubbles,...

PROCESS OPTIMISATION OF MIXED COPPER ORES THROUGH …

Mixed copper ores are treated through different processes depending on the degree of oxidation as well as the consumption of acid. With the availability of real-time technology that can reliably measure differences between oxide and sulphide minerals, it is now possible to control a mixed copper ore …

AN INVESTIGATION OF COPPER RECOVERY FROM A …

improvement of sulphide-oxide copper ores processing through the use of mixed collector systems has surged. The flotation of a natural porphyry copper ore with bornite and malachite was investigated via fundamental work with pure minerals and a bench-scale testing regime. The

Flotation of mixed oxide sulphide copper-cobalt minerals ...

This study investigates the flotation behaviour of a mixed oxide-sulphide ore where copper is hosted in sulphides phases such as bornite, chalcopyrite and chalcocite, and oxide phases such as malachite and to a lesser extent chrysocolla.

(PDF) A Review of the Flotation of Copper Minerals

Copper oxide mixed ore (Type 2) – in contrast to Type 1, this ore type contains cuprite, malachite and azurite as the main copper oxide minerals. Predominantly contains carbonaceous gangue, and ...

Flotation of mixed copper oxide and sulphide minerals with ...

For mixed oxide and sulphide ores, CPS is unsuitable for simultaneous flotation of copper oxide and sulphide minerals, as the sulphides are usually heavily depressed by the sulphide ions from NaHS additions necessary to sulphidise the oxide copper.

Review, Evolution and Optimization of the Kansanshi Mixed ...

The volume capacity of the mixed ore flotation plant increased from 900 m 3 to 1500 m or 2100 m3, depending on whether the 300 m3 cells are used for mixed ore flotation or not. In late 2011, an extension of the CPS plant was commissioned, to increase the number of …

Froth flotation - Wikipedia

For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector stone (although some mineral surfaces are naturally hydrophobic, requiring little or no addition of collector). The particular stone depends on the nature of the mineral to be recovered and, perhaps, the natures of those that are not …

Effect of Desliming on Flotation Response of Kansanshi ...

The Kansanshi mixed copper sulfide-oxide ore contains significant proportions of fine material manifesting in a variety of processing challenges. This stone presents the work which was carried out to evaluate the efficacy of desliming in improving the flotation response of the ore. Two modes of desliming were investigated, namely; sieving and elutriation after which the deslimed material was ...

A New Application For Flotation Of Oxidized Copper Ore

In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed. This ore contains 2.03% copper, 0.15% cobalt and 3.73% sulfur. An effective processing method has not been found to recover copper and cobalt from this ore, which has been stockpiled for 40-45 years in the idled plant.

(PDF) Effect of Desliming on Flotation Response of ...

Effect of Desliming on Flotation Response of Kansanshi Mixed Copper Ore Article (PDF Available) in Journal of Minerals and Materials Characterization and Engineering 07(04):193-212 · January 2019 ...

Copper extraction - Wikipedia

Copper extraction. It is then concentrated using mineral flotation. The concentrate is typically then sold to distant smelters, although some large mines have smelters located nearby. Such colocation of mines and smelters was more typical in the 19th and early 20th centuries, …

A Review on Novel Techniques for Chalcopyrite Ore Processing

: A Review on Novel Techniques for Chalcopyrite Ore Processing . predomin ant copper mineral. Hydrometallurgical methods are used in countries having readily available deposits with low copper content with sulphur of oxidized form at the same time (USA, Chile, Australia and Peru) (Majima et al. 1985). Hydrometallurgical processing of chalcopyrite

Mixed Copper Ore Flotation - quartzcrusher.org

Flotation Separation of Copper Oxide Ore and Other Mixed Ores. The common copper oxide minerals mainly are malachite, azurite, chrysocolla and zigueline. Fatty acids collector has good effect on nonferrous metal oxide mineral. However, with bad selectivity (especially when gangue is carbonate mineral), it cannot improve concentrate grade.
