Copper Flotation - Mineral Processing Metallurgy

19/03/2017  Copper Flotation Process Summary. The flowsheet in this study illustrates the modern approach to porphyry copper treatment throughout the industry. Each plant will through necessity have somewhat different arrangements or methods for accomplishing the same thing and reliable ore test data are used in most every case to plan the flowsheet and design the mill. Flotation of Copper

60 Centuries of Copper: The Flotation Process

The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. 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 ...

Copper-Cobalt ores - Danafloat

Bulk flotation sequence: Under the bulk flotation process, a bulk Cu-Co flotation concentrate is produced at natural pH with xanthate, dithiophosphate and/or MBT, particularly if the copper mineralization is chalcocite. Copper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt minerals. Cobalt depression can be enhanced by small ...

Copper Mining and Extraction: Oxide Ores

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing ...

Copper Production: How Is Copper Made? - ThoughtCo

26/09/2019  Sulfide Copper Ores . Virtually all sulfide-type copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting.After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.

Copper-Nickel ores

Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails. Pentlandite and iron sulphides are depressed by raising the pH up to 12 with lime and a small amount of sodium cyanide. Elevating the slurry temperature to 30-35 degrees C may improve the ...

Resources: Standards Properties - Copper Copper

The pure copper or high copper alloys are made from copper ores that are obtained from the mines as sulfides, which contain zinc, lead and other sulfur. The ores are crushed and milled until they becomes a powder. A technique known as flotation separates the metal from the non-metal components of the powder. The next step is a concentrating stage where minerals are concentrated into a slurry ...

01/11/2019  Sulphide ores are the major source of valuable metals such as copper, lead, zinc, and nickel, as well as gold, silver, and platinum group metals (PGMs), and flotation is the dominant industrial process to recover these metals via the production of a sulphide concentrate. Of total world copper-mine production, almost 80% originates from flotation of the copper (Cu) sulphides . The ready ...

Extraction of copper from minerals • Involves a series of chemical, physical and electrochemical processes. • Depending on whether an ore is sulfide or oxide, the process ...

(PDF) UTILIZATION OF FLOTATION IN COPPER

The froth flotation and behaviors of chalcocite and carrolite were investigated through many flotation tests in order to recovery copper and cobalt. This paper investigates the effect of potassium ...

A cascaded recognition method for copper rougher

16/01/2018  Because of a generally long duration of copper flotation, the frequent changes in ore sources and the involvement of multi-phase bubble overflows and bottom pulp-flow, the recognition of copper rougher conditions by using direct visual features only may easily lead to the fluctuation of recognition results. Furthermore, it makes the control and operation in later procedures more difficult

EVALUATION OF ORGANIC CARBON SEPARATION FROM COPPER

The presence of shale, the source of carbonaceous matter in the ore, has also a negative effect on flotation and pyrometallurgical processes. The presence of clay minerals and organic carbon in shale makes the production of high quality flotation concentrates, without excessive loss of copper and other metals in the flotation tailing, difficult. The reason for the diminished concentrate ...
