Dear Enad,
I feel it would be better for you depend on supply houses for this process.I know that suppliers have this process which gives as much as 106 mg/amp/minute.

Cyanide gold chemistries are common for electroforming gold alloys and are operated at 55-65oC but lower temperatures can be used adjusting the amperage down correspondingly.

Dear Mohan,
Thank you for participating but you must know that most of the chemical compounds which I need prepared myself from individual chemicals to lower cost, and for the difficulty of importation to Iraq.
