mercury processing
Mercury in the bulb of a thermometer.
To recover mercury for reuse after the amalgamation of gold or silver, the process involves a specific distillation technique. After the amalgam is separated from the barren ore, it undergoes filtration and washing to remove impurities. The cleaned amalgam is then placed in a sealed retort and heated. This heating process distills off the mercury, allowing it to be collected and reused.1
It is essential to emphasize that because mercury poses severe health risks, including mercury poisoning, the use of carefully designed, sealed equipment is a moral and safety imperative to protect both operators and the environment from toxic contamination.12
