Also how would I attach the tube to the flask

There is the problem of emptying the gold once the nitric acid has removed the base metals
Would it help to dry the precipitate in a piece of sheet lead, fold the lead and cupel it, or is there a better approach to this?
I would also like a copy of your spreadsheet in Excel if you don't mind. When I click the link i get: The selected attachment does not exist anymore.

This isn't exactly it but it may do unless you need gold with silver by difference. Then I will have to dig a bit.
