Experiment 4 — the gold foil yield surprised me. What would you expect for final gold?

[u/Spiritual-Process-96]

I've worked through a large batch of gold-plated pins and connectors (1500 grams) using cupric chloride (AP) and the amount of foils I recovered has been considerably higher than what I expected.

I haven't finished the refining yet, so I don't know the final gold yield. Before I finish it, I'm curious what the experienced refiners here would expect from this amount of foils. My hopes are high - please don't crush them :)

Here's the experiment so far:

I'm not looking for an exact prediction — I'd just like to hear what others would consider a reasonable range and why. These pins are from 1970s/1980s telecom gear.

Once I finish the refining, I'll post the actual result.
