The crucibles are listed as "one shot" ,however, with some amount of care applied during use one can reuse them many times as long as they are not cracked.
The flux is a proprietary recipe. What I can tell you is that it consists of borax mixture, with a few other typical gold flux additives and a microwave absorbing material that will act in concert with the black sand in the concentrates to be smelted to provide the heating during microwaving.
@djc12c Thank you for your prompt reply. Just wondering if a higher power Microwave oven is used to perhaps provide extra concentration of power and hence heat, would you still need this special flux additive or may be a simpler mix could be used instead? thanks.
@djc12c Okay thanks, It is just that because I live abroad and I imagine that it would be difficult and costly to ship the custom flux. At this initial stage I am just trying to understand and look into various viable options. thanks!
Can you remove gold from electronic circuits boards using this technic, if you remove the excess circuit board material? My email is taftdavidhaynes@hotmail.com
No more than other common processing methods. The typical way gold might be lost is that it is tossed out in the dross/flux after processing as tiny spheres that didn't get mixed properly with the rest of the gold in the melt. Always check the dross before tossing and it can be recovered if there.
In the video a length of coathanger wire was used. This method I don't advise as it could contaminate the melt and there is possibility of getting fingers burnt from the wire conducting heat. There was no proper tool to use at the time of the video production.
.If you start with 24K you will end with 24K. If any other metal such as copper or silver etc. is present that can alloy with the gold it will be something less that 24K. This is not a refining process but a smelting process.
Gold does sink to the bottom of the crucible. The insoluable impurities will mix with the flux leaving any gold or gold alloy at the bottom of the mix..
The mixture used was a typical combination of black sand concentrates containing very small fine gold as well as trapped micron size gold. Larger pickers and flakes were added for the purpose of demonstating that the gold does melt within the crucible. The fine to micron size gold seperated from the black sand and combined with the larger gold to form the final button. That particular run lasted roughly 40 minutes from crucible placement in the microwave to material pour.
I don't understand why you wouldn't set the microwave on its back so the door is on top (opens up), and put the kiln in that way (assuming it fits). Seems like you wouldn't have to remove anything but the lid on the kiln to stir and it seems safer than moving a box with liquid metal in it around all the time.
The optimum (and correct) position for the microwave output is from the side of the kiln. The kiln would only be removed one or two times (if needed) to stir the molten liquid rather than "all the time" Additionally, the crucible is fit within the Kiln such that it won't tip over unless you lose complete control and drop it the whole assembly. You always have to move molten metal in some way whether you use this process or a standard furnace to smelt metal.
The same as with most standard smelting operations - 2 to 4 parts flux for each part of material to be smelted. The purity of the your initial material will determine if more or less is required. .
AMAZING!!!!!!

Hi, thank you for the video.
Are the crucibles only good for one use or do you re-use them?
What is the custom flux mix made of?
Blessings

A higher power microwave will produce a faster smelt, however, the custom flux will still be needed for optimum and proper results.

So the gold after this process is 24k ? i guess as the gold is a heavy metal go to the bottom of the kiln?

was the gold you put in there half black sand? was it able to separate itself? or is it mixed in? how long was the entire microwaving process?
