Flotation of Copper Ores

Flotation of Copper Ores. Treating coarser material or ores that contain a large percentage of heavy gangue such as in the Coeur d’Alene , it has been found advantageous to increase this to as much as 4½ in. per foot to prevent the blanketing of the porous medium by coarse sand collecting on the bottom.

Copper Flotation

Flotation of Copper Ores. In most plants engaged in the flotation of ores containing copper-bearing sulphide minerals with or without pyrite, pine oil is employed as a frother with one of the xanthates or aerofloat reagents or a combination of two or more of them as the promoter.

Copper Flotation

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 paper mills to make bubbles, an alcohol to strengthen the bubbles,

Copper Mining and Processing: Processing of Copper Ores

What is Copper? A. Processing of Oxide Ore. Oxide ores are generally processed using hydrometallurgy. B. Processing of Sulfide Ore. Sulfide ores are generally processed using pyrometallurgy, C. Recycling Copper. In addition to processing copper ores, new and old copper scrap or copper alloys

60 Centuries of Copper: The Flotation Process

The Flotation Process. Today such ores which would be regarded as relatively rich in copper are scarce; the great majority of mines contain the metal in finely disseminated particles which aggregate anything from 2 percent down to 1 percent or even 0.8 percent of copper. Thus to obtain metallic copper, up to 99 percent of

PDF A Review of the Flotation of Copper Minerals

The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu open pit mines and 1-2%TCu underground mines is of great commercial importance.

Mining Industry Copper Sulfide Ore and Flotation Process

5 Copper-nickel ore Copper minerals and nickel, such as nickel sulfide ore and nickel-containing pyrite and pyrrhotite. 6 Copper-cobalt ore Copper mineral and cobalt-containing pyrite and other cobalt minerals. 7 Arsenic sulfide copper ore The ore has a high content of arsenic, which is mainly in the form of arsenopyrite. Flotation

A New Application For Flotation Of Oxidized Copper Ore

The Flotation of Samples with Sulfurization of Oxidized Copper Ore. For the sulfurization process, two samples were prepared in two different autoclave mediums: Sample A containing 18.37g H2S 120.00 g H2O for one kg of copper ore, and Sample B containing 24.50 g H2S 160.00 g H2O for one kg of ore.

Copper extraction

Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide usually chalcocite , which can then be activated by the froth flotation plant.

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper 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.

Mining Industry Copper Sulfide Ore and Flotation Process

6 Copper-cobalt ore Copper mineral and cobalt-containing pyrite and other cobalt minerals. 7 Arsenic sulfide copper ore The ore has a high content of arsenic, which is mainly in the form of arsenopyrite. Flotation process to solve the problem of copper and arsenic separation, reduce the arsenic content in the copper concentrate as much as possible.

MEI Blog: Challenges in copper flotation

Nevertheless, the flotation of copper ores still presents challenges to the minerals engineer. Copper is characterised by having a number of economic ore minerals, many of which may occur in the same deposit, and in various proportions according to depth.

Flotation of mixed copper oxide and sulphide minerals with

At a blend of 70% sulphide ore and 30% oxide ore, the rougher scavenger copper recovery was as high as 95.5%. The copper recovery from the blended ore using a mixture of collectors was shown to be superior to the recovery obtained using only xanthate after controlled potential sulphidisation. 2008 Elsevier Ltd.

A New Application For Flotation Of Oxidized Copper Ore

The Flotation of Samples with Sulfurization of Oxidized Copper Ore. For the sulfurization process, two samples were prepared in two different autoclave mediums: Sample A containing 18.37g H2S 120.00 g H2O for one kg of copper ore, and Sample B containing 24.50 g H2S 160.00 g H2O for one kg of ore.

Froth Flotation Method Gold and Silver Ore Flotation

The vast majority of polymetallic sulphide ores containing gold and silver are treated by this method. When flotation of such ores, gold and silver enter into the copper concentrate or lead concentrate closely associated with them. The products are called copper, gold and silver concentrate or lead, gold and silver concentrate, etc.

Flotation of a copper sulphide ore from Okiep using thiol

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

Copper ores

Copper ores. Sulphide flotation of actual oxide copper minerals such as malachite, azurite is not possible with sulfhydryl mineral flotation collectors and either other oxide type collectors are required or alter-native mineral beneficiation routes must be considered.

Sulphide Ores

Clariant Mining Solutions HOSTAFLOT collectors are formulated to achieve the best possible recovery and selectivity when needed. Our solutions encompass the flotation of ores containing lead, zinc, copper, nickel, cobalt. Our FLOTANOL frothers are customized to help you achieve the right froth to maximize the recovery of coarse or fine materials.

Bioleaching of copper ore flotation concentrates

These results have demonstrated that the bioleaching of Polish copper ore flotation concentrates can be realised in a special bioreactor biorotor . Copper recovery was satisfactory 86% after 13 days treatment . The high copper extraction was achieved in the presence of iron ions 2 K medium or pyrite 3% .
