Well i have read that if you are desolving unpure gold i.e. 14k then you first add salt a bit at a time to precipitate silver, filter the silver solids and then add Sodium Hydroxide or sodium sulphate (Lye) a bit at a time until all gold is precipitated. filter out the gold solids (black dust) then kill the mixture with Lime juice for safe disposal.
