can you suggest to me any alternative bath for copper cyanide to plate copper strike on mild steel? Is it eco friendly?

As far as I know, the better copper pyrophosphate baths are all proprietary. They are offered by several companies including EPI (Electrochemical Products Inc.) [a finishing.com supporting advertiser]. You don't say why you are copper striking, so I don't know if this helps, but you can also nickel strike instead of copper striking.

Do Nickel strike followed by acid copper.
