What acid is used for gold recovery?

Mix 3 parts distilled water or spring water to 1 part nitric acid in the beaker or Pyrex container that contains the gold. Add 10 parts tap water. Filter the gold out of the container through a plastic strainer or funnel lined with a filter. The gold will be clean and pure.

Melt your gold and make shot. This is optional, but recommended if you are using nitric acid instead of a substitute.
Pour the shot into one or more Pyrex or plastic containers.
Add your reagent to the container.
Allow the mixture to sit for at least 30 minutes.
Pour the acid into another, larger container.

What acid is used for gold recovery

Sulfuric acid is used to work with the extraction of gold from chips in the processing of electronic waste. Nitric acid (aqueous fortis and even alcohol nitrate) technical top grade, concentration in water 68%, removes metals back and is used in aqua regia. Hydrochloric acid is 32% used in the recycling of e-waste and is the main ingredient in Turquoise Regia.
