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.

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,...

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 practice,...


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 process.


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.

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.

(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 ...

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 sulphidisation intervals to the current four stages.

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, stone recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

flotation of mixed copper ore

Mixed Copper Ore Flotation . 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. Contact Supplier

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, when smaller smelters could be economic.

Effect of Desliming on Flotation Response of Kansanshi ...

The flotation response of sulfide minerals in the Kansanshi mixed oxide-sulfide copper ore is superior compared to oxide minerals, for the given flotation conditions. The grade-recovery profiles and the flotation kinetics show improved results for …

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.

flotation of mixed copper oxide and sulphide minerals

flotation of mixed copper ore tfg. Segregation Process of Mixed Sulphide Copper Ore. Sulphide copper ores are normally concentrated by flotation while the oxide ores undergo hydrometallurgical treatments. The mixed sulphideoxide copper ores may be processed by combined methods such as flotation followed by leaching and precipitation of the

Copper-Lead-Zinc ores - Danafloat

Copper-Lead-Zinc ores The Cu-Pb-Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage.

Development and optimization of mixed sulphide/oxide ...

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

A Review on Novel Techniques for Chalcopyrite Ore Processing

Flotation has developed from the treatment of simple ores to the ever more complex ones that are being fund today. Thus, for example, the three metals in copper/lead/zinc ore are floated into three concentrates, each containing one of
