Hi Lou. My mind came up with this question (after watching Owltech's excellent videos for the Nth time): How much can the purity be enhanced by extended ripening?. Especially if, on purpose, the precipitation is kept incomplete at say 95% or 90% (by not adding enough oxalic acid, in this case), etc.Lou said:Ripening is best term
Pedantics!
Lou said:I really don’t know.
In general, incomplete Au precipitation’s yield finer purity gold.
