Extractive separation of copper and nickel from
2008-12-1 LIX 84 and Cyanex 272 were used as extractants for copper and nickel separation. 25% LIX 84 was found suitable for complete extraction and separation of copper and nickel in the mixer settler unit. These solutions after separation could be used for metal powder by electrolysis or any other metal salt such as oxides/sulphates.

The Separation of Copper and Nickel from Ni- Cu Mixed
This was observed through investigating the electrochemical behavior of copper and nickel ions separately in acidic mediums of copper sulfate and nicke l sulfate solutions. To selectively deposit copper from Ni-Cu leaching solution, potentiostatic deposition was applied and the current efficiency was studied.

Separation of Copper and Nickel by Low Temperature ...
When copper and nickel enter estuaries they exhibit distinct geochemical behaviours. Copper tends to become associated with solids while nickel remains dissolved. Nickel is thus free to enter the oceans while copper accumulates in estuarine or near-shore sediments. Early diagenesis in pelagic sediments acts to reverse these estuarine effects.

2007-11-15 The separation of copper (II), cobalt (II) and nickel (II) from aqueous solutions is frequently required in hydrometallurgical processing. The applications of liquid membranes offer a potentially attractive alternative to solvent extraction process and combine the process of extraction and stripping in a single unit operation.

2012-10-1 A separation factor range of 93–170 for copper over nickel was obtained in the CaCl 2 concentration range of 100–320 g/L. Considering copper extraction and its separation from nickel and cobalt, a target CaCl 2 concentration of 200 g/L is suggested to be used with the separation factor of copper over nickel and cobalt of 138 and 1020, respectively.

2013-12-24 Separation of copper and nickel by liquid-liquid extraction from aqueous solutions was studied using LIX 664N in kerosene as solvent. Both metals were taken in their sulfate form and ratio of copper to nickel in feed solutions was maintained as 10:1. LIX 664N concentration in kerosene was varied from 10% to 40% (v/v) and its effect was studied

Separation of Copper from Nickel - Finishing
2010-4-21 The scrap value of composite is very poor while if I can separate Nickel and copper, I can get better value of scrap. The thickness of copper is about 50 microns max and Nickel is 150-178 microns. The bonding is too good to be separated mechanically.

2021-6-5 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.

The results showed that the addition of Mextral 984H enhanced the separation factors of copper, nickel, cobalt, zinc, and cadmium over magnesium and calcium. Compared with Versatic 10 acid alone, for a mixture of 0.5M Versatic 10 acid /0.5M Mextral 984H, ΔpH 50 values of copper, nickel, cobalt, zinc, and cadmium were found to be >2.0, 3.30, 2.85, 0.95, and 0.32 pH units, respectively.

Lumpy ore after semi-autogenous milling in Copper–Nickel ore processing at the Talnakh factory is studied. The lumpy ore is mainly presented by sizes −80+40 and −40+20 mm. The X-ray radiometric separation tests of the lumpy ore prove their efficiency in production of concentrate and tailings. The strength characteristics and the Bond work index of the concentrate are determined.
