FLSmidth manufactures Summit Valley Mercury Retorts and vacuum distillation ovens ranging from 0.5 cubic foot to 40 cubic feet material capacity. Both fuel fired and electric models are available. Mercury condensing and handling systems are included with all retort systems. Custom condensing and mercury handling systems can be provided to meet specific customer requirements. Our latest generation of 30 and 40 cubic foot electrically heated retorts have no equal for processing high volume, high mercury materials such as Merrill-Crowe precipitates. These retorts have cycle times of approximately 24 hours and can produce a product that contains less than 0.01% mercury.
