The latest in “Daniel And Roberts’ Demonstration Series” is a two part video. Part one is the preparation and acid dissolution of the gold and Part Two is the precipitation of the pure gold back into a useful form. As usual Daniel Ballard does the Narrations and Robert Lumabao does the demonstrations. If you have ever been curious about all that mysterious alchemy we call Gold refining , give this pair of downloads a try. Taped entirely at Precious Metals West/Fine Gold in Ontario, California.
