- Cna anyone tell me exactly what nickel activators do? I'm looking for a
- nickel activator that is alkaline to use with cyanide gold in a brush plating
- operation. Most nickel activators I've tested are acidic and that's a no no
- around cyanide.
-
- If anyone knows of a alkaline nickel activator or a good looking non cyanide
- gold solution, I would much appreciate hearing about it. Cyanide makes me
- nervous. One potassium aurocyanide solution I sent away for has a p4hof 4.7.
- How can a cyanide be suspended in an acid ????

- Thanks
