The Best Way to Separate Copper and Nickel

Copper often can be found in the nickel-bearing ore, while nickel is always present in the copper-bearing ore. However, industries will always separate the two metals other than end up with an alloy of the two in the process of smelting and refining.

inorganic chemistry Separating nickel coin into copper

To separate the copper, I would suggest that you shake the copper / nickel mixture in hydrochloric acid with 30 % aliquat 336 diluted with aromatic kerosene (or ethyl benzene). Do this in a fume hood. The copper will be extracted by this solution of an ionic liquid in the aromatic solvent and the nickel will be left behind in the aqueous solution.

Jul 08, 2012· Separating copper and nickel Got a solution of an approx 11:1 copper chloride:nickel chloride solution, with whatever other ions come in tap water here in Los Angeles. I'd like to separate the copper from the nickel and both from all other trace ions. I have whatever chemicals can be reasonably found in a high school chem supply closet.

How to separate copper and nickel? [Archive] AlloyAvenue

Nickel will react, slowly, with HCl (and copper does not), but it may only yield acceptable results if you have a finely divided source. Once you have the chloride, separating off the copper should proceed relatively easily via filtration, and then you can electroplate out the nickel or reduce the salt chemically.

Nickel processing Extraction and refining Britannica. In cases such as the Sudbury deposit, where the copper content of the ore is almost equal to that of nickel, the concentrate is subjected to a second selective flotation whereby the copper is floated to produce a low-nickel copper concentrate and a separate nickel concentrate, each to be processed in its respective smelting line.

Separation of copper from nickel in sulfate solutions by

Jan 01, 2017· Mechanochemical activation was used to the separation of copper and nickel. • The CaCO 3 was effective to separate copper from nickel in sulfate solutions. • Over 99% Cu(II) ions were precipitated, while 99% Ni(II) ions remained in solution. • Mechanism of the separation was discussed.

Here's a phase diagram for a copper-nickel alloy, which I think is a system where both components are completely soluble in one another in all ratios. This composition cannot be separated by cooling it down, as I understand it (even though, as mentioned here,the composition would not be uniform if the molten alloy is not cooled down slowly

Nickel processing Extraction and refining Britannica

Nickel processing Nickel processing Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel

Copper-Nickel Alloys: Properties, Processing, Applications

The density of copper (8.93 kg/dm 3 at 20 °C) varies only slightly with increasing nickel content (density of nickel at 20 °C = 8.9 kg/dm 3) and is 8.9 kg/dm3 for all Cu-Ni alloys specified in DIN 17 664. This aspect can also be seen in Table 7 with the physical properties

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

How to Extract Nickel From Copper-Nickel Sulfide Ore?

The advantage of this process is that the copper concentrate with lower nickel content can be obtained directly. 2. Bulk flotation process. Bulk flotation process is used to separate ores containing less copper than nickel, and the copper-nickel mixed concentrate can be directly smelted into high-ice nickel. 3. Bulk-differential flotation process
