I think you will get better advice if you explain step by step exactly what you digested and the steps you have taken to recover it.

Otherwise we are all making assumptions and getting you the right answer simply takes too long.

Plus there is no picture posted.

precipitated from Aqua Regia using sodium metabisulfate, but it did not succeed in precipitating
Just a small detail question: Did you use Sodium metabisulfate as you wrote, or do you actually mean Sodium metabisulfite? A fairly significant difference between those.
I have learned that it is sodium metabisulfite that we use.
