I have 2 pounds of scrap gold, 14 & 18kt I would like to smelt at home
for resale. Dealers offered 85-90% of gold content and you do not know
if you are getting a straight count. Are there inexpensive methods to
refine this scrap into pure gold.

Such a little beast exists. It's called a Turbo Smelter and operates out of
propane. It's made in Canada by Mill Ore Industries, Timmins Ontario.
Here is their link:

Please log in for more thread options I think the real question was about purifying the scrap. It is simple
to melt gold in a crucible with an OA torch, but you don't know what
alloys you're dealing with. If you try to sell re-melted gold, you will
be required to furnish a certified assay.
There are two common ways to purify it. Chemical solution and selective
precipitation; and electrolytic deposition. Neither way is cheap.

would seem to me that you're going to have to provide an assay to a
serious buyer in any case. You'll recover your costs from the buyer
with increased confidence. -Mike

Please log in for more thread options We have been using Hallmark Refining for many, many years and always
found them to be honest, pleasant and efficient.
We generate a lot of scrap containing silver. Since we melt metal and
work with chemical treatments of metal I have looked at both approaches
over the years. I pretty well determined that it would be a lot of
money and work for a product that would be unsaleable.
It would be fun to do.
