Mercury can be introduced in several ways – one is to rub it on the bottom of a pan, pour in a solution of the cleaned slurry and water and then agitate the mixture. The gold combines with the mercury, which can be scraped off the pan with a spatula. The alloy must then be treated, either with heat or sulfuric acid, to recover the mercury.

The initial step in the gold refinery process involves the extraction of gold ore from the ground. This is done through mining methods that depend on the location, accessibility, and quality of the ore deposit. Underground mining techniques, such as tunneling and shaft mining, are employed to extract gold ore from deep within the Earth.

Fortunately, at-home testing isn't hard. You have three basic methods at your disposal: Magnetic Testing- Touch a magnet to the specimen. Pyrite is magnetic, gold isn't. Density- Measure the volume and weight of a gold-bearing stone. Quartz has a density of 2.65 g/cm³, while pyrite sits at 5 g/cm³. Gold will be 19.3g/cm.
