By placing powdered ore in the mouth of a tobacco-pipe, closing the mouth with clay, and exposing the bowl to a fair heat, the mercury may be collected on a cool surface, held so that the fumes given off may be condensed. A gold coin or a piece of clean copper placed in the fumes will soon have a deposit of mercury on its surface.

Mercury readily forms alloys with other metals, and this makes it useful in processing gold and silver. Much of the impetus to develop mercury ore deposits in the United States came after the discovery of gold and silver in California and other western states in the 1800s. Unfortunately, mercury is also a highly toxic material, and as a result ...

The shaker table was lined with copper plates coated with mercury. The gold specks would stick to the mercury and the rest was flushed into the can-yon bottom. It was then a matter of cooking off the mercury to leave a small blob of gold behind. This last part of the process would work only for the ore extracted from the Cross vein.

Put the rock powder in a mining pan. A mining pan has holes in the bottom of it like a colander. Because gold is heavy, it will sink to the bottom of the mining pan even while it's submerged in water, while the other minerals wash away.
