Mercury in the bulb of a thermometer.
In the United States, rotary furnaces are favored for mercury processing primarily due to their ability to handle higher capacities and support continuous operation compared to other furnace types.1
These systems offer several operational and safety advantages:
- Efficiency: The use of mechanical feeding and discharge mechanisms facilitates a continuous process, which is more efficient than batch-operated retorts.1
- Safety: Automated handling significantly reduces worker exposure to hazardous mercury vapours, sulfur dioxide fumes, and dust.1
- Cost-effectiveness: By automating the feeding and discharge processes, these furnaces effectively lower labor costs.1
