Using Chapman flux to remove gold from black sand

Getting all of the fine gold and flour gold out of your black sand can be a challenge. Using the Chapman style gold refining flux can make the job go allot better. In this video, I use the flux in a graphite crucible only because I have allot of them. You can use any type crucible you choose. The Micro-Mini furnace works great for the process but any type furnace, kiln or torch can be used. Had some trouble getting "Manganese Dioxide" out.
