Same idea, use a box to catch the small bits, no heat - de-populate with a roofers hatchet.
Pons and fingered ram in a tumbler abrade the gold off, by pulling the pins like he did in the video He's getting a tad more gold over the method I use as the solder acts as a collector.
My method is faster, no nitric acid used at all, just a bit if cyanideand a dash of peroxide, the gold is plated onto steel wool then dissolved in dilute sulphuric acid leaving the gold behind.
The flower pot, a fellow gave me all his waste solutions, I cemented everything down as metals using scrap iron which were primarily copper. The copper sponge went into the unglazed flower pot. With electrolysis plated the copper over to the copper sheet leaving the gold behind in the flower pot.
The brown liquid is super saturated with gold, filtered over to the Vision ware pot waiting for further refining.
