Just do them directly in hot ar

Nope sorry but that's wrong old mate.
Drop the white off with a hammer and a face mask first otherwise you won't get to the goodness underneath.
Common sense needs to be applies here. Don't make dust and mitigate it. The results are very nice but find a leaching process rather than dissolving all the base metals.

But still not sure how I can process such type of material

Ok great .. what leach method is preferred with this .. personally I tired diluted HNO3 with one of these power RF transistors but it didn't work ..seems it's not just copper there as I got a white mud with the foils (not tin)
Using Nitric like this is a dissolve not a leach. Although personally if you have done this I would decant the liquor and retain the powder and foils and add HCL to make AR and dissolve the gold, denox, filter and drop. Leaches that would be applicable are Iodine/Iodide (relatively expensive and you need a good understanding) or Cyanide (which respectfully I don't think you are ready for.)
Also, should I remove the while cap 1st ? and how I can do this while avoiding Beryllium/BeO ?
As mentioned by Goran it it entirely possible that it isn't BeO but my comments about removing them still apply.
Does any one have an estimate for the yield of these kind of material and does it worth ?
Yes it's worth it. I recommend you do your own assay based upon keeping notes of your results.
