Copper deposit is growing on plastic surface during electrowinning
April 5, 2012
Q. Hello,
I am electrowinning copper from copper chloride in a divided cell. I'm using mainly gelatin as additive.
The thing is that my deposit grows on non conductive surface too. For example it grows on adhesive surface and polypropylene surface.
I experimented the same thing while testing copper electrorefining with copper sulfate.
Can anybody explain why the deposit can grow on a non conductive surface and cover it?
Thanks,
