Instructions
Fill a large plastic container with coconut carbon. Coconut carbon is activated carbon that has been infused with oxygen and has a large surface area. It adsorbs gold and other precious metals from water.
Fill a plastic bucket with water from an old abandoned flooded gold mine or other water source.
Pour the water slowly on top of the coconut carbon and allow gravity to feed it and filter it through the coconut carbon. Allow the water to pour out through the hole in the bottom of the container.
Repeat many times until the coconut carbon becomes heavier and saturated with precious metals.
Take the container with the coconut carbon to a precious metals refinery. Instruct them to burn the coconut carbon in a muffle furnace, which goes up to 1,000 degrees Fahrenheit. Carbon ash will be left, which the refinery will filter through a coffee filter, leaving the precious metals in the filter as a fine powder. The precious metals will then be smelted into dore bars in another similar furnace. A dore bar is a mixture of gold and other precious metals in a solid form. The refiner will separate the metals in the dore and make you an offer on the precious metals found in your coconut carbon, if any.
