Alternative chemical to Sodium Cyanide used in Gold Strippin

[Prakash2015]

Dear All,
Greetings.. I am new comer to this site.
I am working in a jewelry form as a senior manager Productions manufacturing 9-18 Yellow & white Gold, Platinum Palladium & silver jewelry of studded & plain variety.
We do a lot of plating of white & yellow gold jewelry. As most of our jewelry is wax set ( stone in cast), we have to perform a stripping process by Sodium Cyanide our cast pieces after castings.This give a clean look below the diamonds & removes any blackened stones or surface if any below or on the diamond seat caused duet to high heat during castings.
Can anybody guide me as to if there is any other alternative chemical, that we can use for stripping other than sodium Cyanide,???.
As I am very scared of using this chemical & as well as storing this chemical in our factory premises as I am not comfortable to storing Sodium Cyanide as it may get misused by others while handling.
Awaiting for your response,
Best regards,
Prakash Pai
senior manager Productions

Sure!!!!!!!...Bromine process,Iodine process,Thiourea process,Thiosulfate process BUT all of them have drawbacks in comparation with NaCN process.Use the search box with any of these alternative processes and you can take a look.

In my case I am working on Iodine process,it is nice,fast,no fumes,non toxic but extremely EXPENSIVE...How much expensive?...well,here in Mexico 1 kg of NaCN costs $120 mexican pesos,1 kg of metallic iodine costs $4000 mexican pesos...I konw,I know..metallic iodine could be recycled,anyway...all information about these processes is right here.

Hope it helps.

Kindest regards.

Manuel
