Refining 26 grams of dirty gold powder recovered from electronic waste, Part 1.

In this video I show how I refine 26 grams of dirty gold powder recovered from various types of e-waste. The gold is contaminated with base metals, silver, platinum group metals, trash and oils. In part 1 the gold is refined to remove base metals, silver and trash. In part 2 the PGMs will be removed. please visit http://www.mdpub.com/UrbanGoldMining/index.html for more information.
