Cyanide plating on jewellery products


#1

Dear folks,

If any body is expert in gold plating with Cyanide pls. share the
details.

Also give the expert opinion on non-cyanide plating on jewellery
products (especially on 22 kt gold chains) Since we are in India,
using Cyanide is very difficult, our Govt. is not giving licence to
this kinds of processes, as it is contaminating environment.

Expecting right solution on this would be appreciated.

Thanks in advance.

Best regards,
Kumaravel. R

If the government is banning the process because it is
environmentally disastrous -even on a small scale- why would you
consider it for your operation? Please make the right choice for you,
your employees, your neighbourhood and your environment and go with a
safer electroplating method or just a solution that requires no
electricity to deposit, albeit, micro-thin layers of gold or any
other metal to colour the base metal product or to reduce or help
prevent corrosion ! Yes, potassium cyanide works great in stripping
and plating baths and can be done quickly for small batches with a
simple battery, anode(a strip of 24 kt gold or even a coin can be
used), cathode and a stainless steel bain marie (like food services
use) but it is outdated considering the ready-to-use ecologically
more sound solutions out there that are far less dangerous.

University of California at Davis has a good site called "Chemwiki"
that outlines the electroplating process on different scales of
production as well as problems and solutions to them- it’s a good
starting point to learn about the process. Also, any jewellery supply
vendor’s catalogue has ready made plating solutions and set-ups (in
most cases) that could get you started relatively inexpensively with
or without direct current or a closed cell (a battery).Try to avoid
cyanide, particularly if it is known to you to be illegal! rer

If the government is banning the process 

Where can I find on this? I know that 2 states ban
cyanide for mining, but I can’t find anything on more widespread or
inclusive bans.
