Apr 21, 2010 · The thickness of copper is about 50 microns max and Nickel is 150-178 microns. The bonding is too good to be separated mechanically. Because the nickel is more valuable and three to four times as thick, it sounds better to strip the copper from the nickel than vice versa

And in this text, Amisy, the expert of copper recycling machine, will introduce an effective and relatively inexpensive way to separate copper and nickel. At the beginning, you need to prepare an ore composed of copper and nickel. Then, find some equipment to crush and grind the ore, and separate out the worthless material by the method of flotation, which will leave you a concentrate that typically composed by 2% …

separation of copper and nickel by solvent extraction

Another method of separation of copper and nickel has been proposed by Giannopoulou and Panias[13] by electro recovery of copper followed by nickel precipitation through neutralization. In this work separation of copper and nickel is carried by selective extraction of copper and nickel at different pH followed by the stripping of the respective loaded organic phases for recovery of copper and nickel

Copper-nickel separation technology is divided into two types: copper-nickel mixed concentrate separation and high matte separation technology. Generally, the former is used for copper-nickel minerals with relatively coarse grain size and not closely related to each other, and the latter is used for copper-nickel minerals with fine grain size and densely interspersed ore

separating copper from nickel by electrolysis

separating copper from nickel by electrolysis

Jun 24, 2008 · Electroplating shops routinely purify their nickel solution by "dummying out" the copper at low voltage. In principle electrolysis can be used, but how best to do it depends on your actual circumstance (volumes, ratio of nickel and copper in solution, what you will do with the copper, what you will do with the nickel, what other metals are present, what acid they are dissolved in, etc., etc.)

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
