An apparatus for the recovery of heavy metals from a heavy metal-contaminated material wherein the heavy metal, or particles containing the heavy metal, are separated from the material by a hydraulic mineral separator. The apparatus may be used, for example, in removing or recovering of mercury from a mercury-contaminated soil, caustic sludge, or similar material. The apparatus allows for continuous operation of the mineral separator and automates various functions of the separator allowing for improved control of the process. IMAGE
