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,
