T-Hawk, perhaps this will help.

For a good, readable, description of what they're doing, read https://www.911metallurgist.com/blog/op ... on-process. (The website has a lot of good information.) Scroll down to the design parameters table and you'll see where they agree with 8's estimates. For the purists among us, look at http://www.denvermineral.com/Pdfs/Merrill-CroweS.pdf. That's the original method description. There have been a lot of tweaks to the process since then.

I think the recovery range is based on how much zinc powder was used as well as how much copper, lead, and other minerals are also dissolved. Oh yeah, if you use too much calcium on the heap, you'll have some of that in the tray, too. In other words, while amateurs can do it, to do it right takes a pro.

I doubt that all of the factors can be predicted ahead of time, hence, lots of "tuning" and maybe even some additional equipment/steps to optimize the yield. However, it's definitely worth the wait.
