The amount of mercury in the amalgams formed by the artisanal gold miners depends on how strongly the miners squeeze off the excess mercury using a piece of canvas. Usually manually squeezed amalgam contains 60 to 70% gold. When the amalgam is filtered with a centrifuge, it can contain up to 80% gold. Forming gold amalgam

By applying heat to the amalgam, the mercury is burnt off as a gas, which passes along the pipe to re-condense as a liquid. The gold remains in the distilling chamber of the tank, while the mercury is collected at the discharge end in liquid form.

The amalgam is then combined with bits of old steel into a large metal drum called an amalgam barrel. This barrel is slowly rotated for up to 16 hours. This ensures that the gold and mercury is fully combined. The Gold-Mercury amalgam is placed into a clay container called a retort. The retort is completely sealed.

The miner stands in the barrel with the mercury laden water and silty-like sediment and mixes the sludge with his feet.

An efficient method to separate mercury and gold from amalgams is by heating above 350 °C. Mercury becomes volatile leaving gold behind in solid state. A retort is a container in which the gold-mercury amalgam is placed and heated; volatile mercury travels up through a tube and condenses in an adjacent cooler chamber.
