Talk:Wohlwill process

If the refining outcome is stated as a percentage purity, wouldn't it make sense to state the purity of the cathode in percentage as well, instead of karat? — Preceding unsigned comment added by 125.253.99.68 (talk) 08:45, 14 August 2011 (UTC)[reply]

Needs some technical details[edit]

What happens to the silver in the anode? I suspect it precipitates out as silver chloride but do not have a cite.
What happens to the PGM in the anode? Why doesn't this material end up in the cathode?

Here is an online resource with some details on this process. The publication date was munged by OCR but looks like July 1918.

Purity from Miller process?[edit]

Stated as 99.5% here, but as 99.95% in Miller process article. (Attributed to same source(s)) — Preceding unsigned comment added by 70.72.144.66 (talk) 17:36, 14 August 2013 (UTC)[reply]

Needs clearer chemical description[edit]

This doesn't make sense:

"Gold and other metals are dissolved at the anode, and pure gold (coming through the chloroauric acid by ion transfer) is plated onto the gold cathode."

What is the structure and source of chloroauric acid?

The overall goal isn't clearly stated. Is the goal of the process to convert 95% pure gold to 99.99+% pure? — Preceding unsigned comment added by 169.253.194.1 (talk) 18:46, 16 April 2014 (UTC)[reply]
