Our Mercury Retort is designed to remove mercury from gold sludge using vaporisation. The unit comes programmed with a standard temperature profile for the vaporisation of water, followed by the vaporisation of mercury, meeting temperatures between 200° C and 600° C. Each cycle takes approximately 20 to 24 hours, with heating time around four hours, soaking time extending up to 16 hours and cooling time of around two to six hours. The amount of time required can be altered, depending on site-specific conditions, such as increases in moisture content. The temperature can also be adjusted, depending on your needs.

 

Supplied as a complete system, the retort oven includes a mercury condenser train, consisting of tube and shell heat exchangers, a mercury trap, dual coalescing/HEPA filters and a final sulphur impregnated carbon bed. The internal oven components of the retort are made of grade 253MA stainless steel, and the exterior is made of carbon steel, making it incredibly robust and durable. It comes in two distinct designs; barrel-style, primarily for electrowinning sludge, and cabinet-style, designed to suited Merrill Crowe circuits.
