The mud is pure gold.
When all the acid is poured off, add tap water to the mud. Stir and let the mud settle. Pour off the water into the container with the acid. If you have a filter, use it. Do not pour off any particles of brown. Repeat this rinsing 3-4 times or more.
Rinse once with aqua ammonia. White vapors will appear. The aqua ammonia cleans impurities from the gold mud while, at the same time, it neutralizes any acid still clinging to the gold mud.
Give the mud a last rinse, this time with distilled water.
Using distilled water, wash the mud into a small Pyrex beaker Visionware pot. Give the mud a chance to settle and then pour off the water.
Put the beaker on a hot plate to dry the mud. Do not preheat the hot plate or thermal shock may cause the beaker to break.
Melt the dried mud (now a powder). If using a torch, first wrap the powder in tissue paper and then soak that in alcohol. Also, use a Burno crucible, this will keep your gold from being blown away by the gas pressure from the torch. The gold will again take on the appearance of metal. If you’ve followed the instructions carefully and used filters, the gold will be 999.5 % Pure with virtually no losses.
