I am working on a concentrate with 9% Silica and 7% Au encapsulated inside of the Silica, according to ICP-MS.
The gold is nano sized gold.
What would you use to dissolve the Silica? I am looking at Alkali-washing but don't have a great way to bench test it.
What can be used to leach the nano Au following that treatment and precipitate it?
Does anyone know of any refineries that would be interested in processing this type of material in bulk?
