Gold Potassium Cyanide

2001

Dear reader,

I am facing a problem with the manufacturer of gold potassium cyanide. I require some knowledge about the manufacture of gold potassium cyanide, the % of gold potassium cyanide used in the electronic industry as some people are requiring 99.5 % of g.p.c.

Please let me kindly know about the ratio.

Thanking you for the reply.

Dear Sir ,

As many mfg of PGC , the percentage is range from 67% to 68.3%, ± 1%, this is the standard practice ,how do you get 68.3 % ? Assuming the bottle total weight is 100g , 68.3grams will be gold and the balance will be potassium cyanide. 31.7 grams. if you want 99% of gold , meaning the balance 1% or 1grams is potassium.
