FIELD: chemistry.
SUBSTANCE: ground raw material is heated to the melting point of gold, the molten material is poured out into a container heated to 92-98°C, and after gold is deposited on the bottom of the container as a solid fraction, and mercury is deposited on the gold layer as a liquid fraction, mercury is separated from gold by removing liquid mercury from the container in a separate container.
EFFECT: reducing the environmental pollution.
