Weight loss refining to pure gold

[shannon flagg]

By whatever methode I would like to know how much weight I will lose refining the following (please explain your formula):
* I have 30 grams of 22.1k Alaska gold nuggets, 20 mesh, and want to guesstimate what the final weight will be after refining (however many times it takes) to get 9999 gold.
- Note: The 22.1k was the average of several scans done with a calibrated XRF Gun.

Your question do not make a whole lot of sense, as it is unclear what you are asking for.
So what are you looking for?
Methods to refine or the theoretical content of Gold in your nuggets?

Have you studied the introductory links?

guesstimate what the final weight will be

(22.1/24) x 30 = 27.625g

Is that what you mean?

Say 27g to allow for some losses in the process.

Yes thank you. I knew it was something simple.

Since you didn't include a picture of the sample, we are guessing there may be some black sand included. For what it is worth, 20 mesh barely qualifies as nuggets, at least in my book.
