The separation of different minerals based on differences in density, surface tension effects and general relative settling rates of the different media over a range of particle sizes is effected in a unique hydraulic mineral separator system. The system and process are particularly useful in the separation of mercury from mercury contaminated soils, sands, gravels, clays and process sludges, (such as chlor-alkali sludges). Sonic vibrations are used to enhance recovery of finely divided mercury and conditioning agents are also used to advantage to reduce surface tension effects and further enhance recovery.
