After being in my studio for 25 years I have just finished
remodeling no crack walls or falling down ceilings to worry about any
Which brings me to my question. I have taken all my floor sweeps and
polishing machine dust that has been adding up over the years and
put them into a crucible and burn it out in a kiln to the point that
I have a very fine dust. I know there is gold in there as I have test
samples of it with a torch and flux. But what can I do next to get
I did my bench sweeps in the same manner and then heat them up in
the furnace at a friends foundry and poured off the gold but there is
alot of ash still sitting on the top after a full day burning it out.
(which you can still see the gold in) So what to do with the fine
dust? I have read about adding lead but not sure how much to use or
what I am looking for.
Any help would be appreciated.
I am doing this to learn as I have nothing to lose as I will be
sending the end results to the refinery in the end as I do not want
to play with the acids to do the final step of separating the silver
from the gold.
