Refining and testing procedures for 4N gold

Latest comment: 18 years ago1 comment1 person in discussion

what about four 9s of Gold? i.e. 999.9 pure gold? Can anyone help me in finding out the difference between 999 and 999.9 gold. I know that the difference is 0.09% purity difference. But I would like to know the refining procedures and testing procedures between these two purities. — Preceding unsigned comment added by 122.169.141.80 (talk) 15:05, 2 April 2008 (UTC)Reply
