Hey guys,
Really appreciate some help.
I have a big bag of polishing “dust” which I have burnt and incinerated into a fine powder. (Mainly consists of high grade 18kt gold.)
Looking to melt this into a bar which then I can XRF and.
How should I do it. What’s the composition of the “flux” I’ve done allot of reading into mixing with borax and melting it? What temperature do I do it at and how and in what. I’ve got a 1kg electric furnace for melting normally jewellery.
Any advice or help is much appreciated. (I don’t want to chemically refine it yet)
Also want to do it myself as I’m not sure how much gold is in there over time - so don’t want to drop it to a refiner.
I tried melting a small bit of it directly in the furnace but it turned to a glassy piece of lava rock.
