Refining 14K Gold to 24K without Nitric Acid / Gold Recovery from Jewelry at home

I´ve put a lot of effort into finding a way to refine gold without nitric acid. As Gold alloys are hard to dissolve with common chemicals, i had to resort to electrochemistry. I´m only using HNO3 for removing silver from gold powder and for the aqua regia. Both steps aren´t necessary and I discuss alternatives in the video.
Small Error: At 4:14 I meant to say Kathode
