Make Black Powder Quick and Easy — Skylighter, Inc.
Keep any mill dust, or completed black powder, tightly covered and in safe storage. To separate the mill dust from the ball mill media, put a round 20-mesh screen into the mouth of a bucket that is the right size to hold it. A screen-type colander that is about 20-mesh works, too. The screen should be firmly attached to the frame of the colander.

United Nuclear - Uranium Extraction Experiment
Place the barrel on the mill and let it run for approximately 2 hours. This will reduce the ore into a very fine dust. This is necessary so the extraction chemicals will be able to react with the ore material. If Ball Milling is not done, very little Uranium will be extracted. After 2 hours of milling, the ore is as fine as Talcum powder.
