An apparatus for separating sulphur and soil consisting of a liquid sulphur bath container having an upper compartment, and a lower compartment. The upper compartment has a bottom sloping downwardly from a peripheral top edge toward the lower compartment. The upper compartment has a lower sidewall adjacent the lower compartment with a liquid aperture whereby liquids communicate between the upper compartment and the lower compartment. A heating element is disposed in the upper compartment to maintain the temperature of a liquid sulphur bath. Solid phase sulphur contaminants in soil are heated to liquid phase by the liquid sulphur bath. As sulphur contaminated soil is placed into the liquid sulphur bath, a displacement of liquid sulphur occurs which results in a migration of liquid sulphur through the liquid aperture in the lower sidewall into the lower compartment and ultimately through the outlet. A belt conveyor extends parallel to the bottom of the upper compartment and through a slotted opening in the lower sidewall of the upper compartment below the liquid aperture into the lower compartment. A layer of soil is carried by the belt conveyor to a spillway positioned adjacent the top peripheral edge of the container. The belt conveyor is of a filter material such that liquid sulphur passing through the liquid aperture into the lower compartment passes through the filter material of the belt conveyor thereby removing sediment from the liquid sulphur.
