I have my previous post reread several times, and I found no claim that nitric is best route for claiming Au from BeCu. None. It was just a report of what happen when you use nitric, as an addition to part of Alondro claim regarding solubility of Be in nitric.Why use expensive Nitric when you can use cheap HCl, then filter the Gold out.
Then you will have to safety treat the Be bearing solution for waste and safe disposal.
That report was intended to help e-scrapers deal with springy connector such as found in RJ45. The good ones are commonly made out of BeCu with Au coating. As a scrap you may find some solder on it as well. So you will find 2% to 3% Be, trace amount of Au, and some Sn with Pb or other solder. The rest 95% to 98% is Cu.
Now, have you ever try and succeed to dissolve mainly Cu compound with your claimed cheaper priced HCl? You can't.
With nitric you can dissolve Cu even Pd and Ag, leaving you with solidus Au that you can directly filter out. But this is not the case when Be is in the mix. The Be will percipitate and/or filtered out together with solidus Au. Even in lower pH there will be some gelatinous Be that will stay at filter. Dead end here, and I am here now. I plan to continue this now binary Be+Au mix with AR.
