Lead removal via soil washing and leaching SpringerLink
A soil washing and leaching process was tested for removing lead from soils. A soil-washing circuit, including size and gravity separations, was employed to remove the coarse metallic lead particles, while the leaching was applied to remove fine metallic lead particles and soil washing and leaching process was tested for removing lead from soils.

Simplified soil washing processes for a variety of soils
A soil washing process is described in which high shear mixing, sprays, hydrosizing, flotation, and screening are integrated to countercurrently clean sand, silt and clay. Chemical techniques are summarized that can be used to remove selected contaminants from the soil and then clean the wash water for reuse. Descriptions of Soil washing systems are quite flexible in terms of number, type, and order of processes involved and other names are used for soil washing technologies: “soil separation”, “soil recycling”, or “volume reduction”. The gravity concentrators such as jig, shaking table and spirals can be affected by particle size effect during theSoil washing for metal removal: A review of

Lead and Zinc Recovery Overview Lead Removal via Soil
tested for removing lead from soils. A soil-washing circuit, including size and gravity separations, was employed to remove the coarse metallic lead particles, while the leach-ing was applied to remove fine metallic lead particles and other lead species. The soil-washing tests proved that the metallic lead particles larger than 0.15 mm (100 mesh)However, there is a huge limitation for the application of washing method in heavy texture soil during the washing method applies to remedy heavy metal-contaminated soil. Moreover, it is unsuitable for the application of washing technology if the soil with a permeability coefficient lower than 10−4 cm s−1 or the clay content is >30%Simplified soil washing processes for a variety of soils
