where to find nickel
I need nickel for making Rayners nickel and I tried dissolving sheels from neodymium magnets (I was thinking it is Mu-metal, but it was iron) than I
tried transformers core but it was again only iron coins have nickel but not ours from Czech rep. and I don't want to buy it direcly on Ebay it is
expensive... so from where can I isolate? thanks for reply...

I know you are not in the eurozone, but the euro coins have nickel in them.

stainless steel scrap will have around 10% Ni and 18% Cr, depending on the grade
also rechargeable batteries Ni-Cd and NiMH

I will look at it but when I get it how can I separate it from Fe Cr and other elements?

E.g. Ni and Cr form water soluble ammonia complexes, Fe does not.
Cr is amphoteric, Ni is not.
But an old, large NiCad battery from a cordless power tool may be you best bet.

Try Polish zlotys (PLN). 10gr, 20gr, 50gr and 1 zloty coins is about 25% nickel, the rest is copper. The silver piece of bimetallic coins (2zł and
5zł) is also cupronickel. 1PLN coin has weight of 5g and is worth about 6,09 CZK (0,23 euro), that gives you "price" of about 4,8CZK (0,184 euro) per
gram of Ni. The cheapest source are however 10gr coins. Weighting only twice less (around 2,5g) but being worth 1/10 PLN nickel extracted from them
would cost you less than 1CZK (less than 0,04 euro) per gram.

There are these Half-Franc coins if you can find them.

Doesn't wikipedia or someone mention that 1955-1981 Canadian nickels are .999 Ni? You can buy these in large bags if the size is right, you have
credit cards, and your package inspectors are OK with foreign coins.

Why bother with coins or other metal scrap if you can buy very pure nickel for decent prices. Think of it, how many grams does a 1 euro coin have. And
then, the nickel is alloyed with other metals, there are two different metals in these counts. The same with zlotys which apparently contain 25% of
nickel mixed with copper.
A much better option then is this: http://www.ebay.nl/itm/NICKEL-metal-99-9-Purity-metal-elemen...
A full 100 grams of very pure nickel for less than 10 euros (plus shipping).
Or have a look at this: http://www.ebay.nl/itm/NICKEL-metal-99-9-Purity-metal-elemen...
85 grams of very pure nickel at appr. EUR 10, including shipping!

I found some NiMh batteries but in them there is sooo many other elements is possible to separe nickel from rare elemets by ammonia sol.? and if I
want to separate nickel and copper must I use electro chem.? or it is easier somehow to percipitate one of them?

Here's some 99.9% Canadian nickels at $14.60 a pound but in the U.S. I bought some for around $55.00/5 lb. last year or so.

Thermite from an oxyde maybe?
It might not be very pure, but depending on the quantity you need you might find some blobs here and there.
Also, isnt it used in special purpose welding? Might be a source there.

There is a lot of high purity nickel on eBay for $10-$15/lb. It is used in electroplating so it is readily available. Nickel metal buttons are a
common form, and blocky pieces, and those Canadian nickels (which are truly nickel).

It doesn't seem like making raney nickel is a cakewalk or rather it seems like you could run up against variables in it's surface area properties and
the cautions that go along with it when working with it.

Certainly any process that starts with mixing melted metal is not going to be trivial, but
I suggest looking at Raney's original patent: US 1,628,190 for insight on how to actually do this.
He describes preparing the catalyst also by breaking the alloy in "pea size" or smaller (not just finely ground) before doing the leaching. This
variation might be more easily accomplished by the amateur.
Another variation is to acquire nickel powder (more expensive, but not compared to buying Raney nickel) and aluminum powder and ball-mill them
together and use "reaction synthesis":
http://web.ornl.gov/info/ornlreview/rev28-4/text/alumin.htm
That is, pressing the powder into a crucible and heating it to the melting point of aluminum, where an exothermic reaction begins which melts the
metals and prepares the inter-metallic compound. The problem of mixing the molten metal and dissolving nickel in the aluminum is thus eliminated.

@CrossxD Are there any electronic cigarette stores where you live? Look for some Ni200 wire resistance coils. Ni200 is 99.6% Ni, just make sure the
coils are clearly labeled.
I got a 10 m coil for like 4 euros.

We've been reading some of the same things maybe and the Ni powder is not too expensive...I've been meaning to try this large in my back yard on July
4th but keep forgetting. Raney did patent the thermite route: US2139602.
2Al + 3NiO -> 3Ni + Al2O3
5Al + 3NiO -> 3NiAl + Al2O3
Or perhaps an ordinary Fe2O3 composition can be used instead...to heat a graphite crucible loaded with Al powder and nickels, and the exotherm
completes the reaction.
EDIT: Well now the Chinese say NiO will substitute, sintering at 950C produces a NiAl/Al2O3 composite they say.

Is it possible to form nickel carbonyl if raney nickel were to catch fire or would you need a carbon source other than the minute amount of CO2 in
air? CO2 in air is 400 ppm and nickel carbonyl at 3 ppm is "LD50 for a 30-minute exposure has been estimated at 3 ppm."
(See page 3 Fire Hazards)

If you have access to cupronickel coins where you live, it can be separated by elecrolysis:
www.sciencemadness.org/talk/viewthread.php?tid=16811&pag...
Otherwise, buy it in bulk as others have suggested.

my plan was make rayners nickel by decomposing nickel oxalate https://www.youtube.com/watch?v=4gO92eqQcB4 or react nickel salt with aluminum powder and than dissolve in alkali base aluminum will dissolve and
nickel will stay as fine powder and that vacuum filter can it be done?

A few more easy sources I have not seen mentioned yet:
1) nickel electrodes for stick welding cast iron. You can easily scrape the flux of to get fairly pure nickel rods.
2) various nickel salts and nickel oxide powder are sold in ceramics supply stores for use in glazes.
3) There are plating sets for plating nickel onto copper circuit boards. I am not sure what nickel Salts they contain exactly, but should be
reasonably pure and way more cost effective than melting down coins
