Interesting Nuggets (of information)

Another great video I found from Goldnscrap got me motivated to do 
a bit more searching.

Chloroauric acid is the result of dissolving gold in aqua regia.You don't buy chloroauric acid, you make it by dissolving scrap gold-plated electronic parts in aqua regia. It is only gold chloride while it is in solution. Once it is precipitated out, it is gold.

One comment I found interesting

You use elemental mercury to form a gold-mercury amalgam which is easily separated from the sand. You place the? amalgam in a hollowed out potato and throw it in the fire. The mercury part of the amalgam gets absorbed into the potato, leaving behind gold nuggets. I'm curious to see if this would work.

To filter

To filter it I believe a simple coffee filter would work if not than you need a peace of corrugated metal, angle it 20 degrees or so than pour it out since gold is heavier it will just stay on the metal.  Similar principle to panning.

Aque Regis Tip

Aqua regia (a mixture of nitric acid and hydrochloric acid) will dissolve silver as well as gold. So if your jewellery is less than 24 carat gold, your solution will contain silver and the metal recovered will be a gold-silver alloy. Silver is not used in electronic connectors because it tarnishes too easily. So if you recover your gold from that source, it should be almost pure. (i.e. 24 carat)

Drying the gold powder

Before drying, wash several times with distilled water, then decant as much water as possible.

Place on low heat and start evaporating the water slowly, as it dries, swirl and shake the beaker lightly to agglomerate the powder to ball & chunks. When the powder is only moist, turn up the heat to medium and keep swirling every now and then until complete dryness. Collect. Melt.
