Abstract: The invention provides a method and apparatus of removing contaminants such as salts, hydrocarbon, chemicals, minerals, and metals from materials such as sand, soil, gravel, drill cuttings, and other solids, and reclaiming contaminants and materials for reuse. The invention is scalable in size and capability, economic to construct and operate and reliable in operation and performance. The invention slurries contaminated material with a solution. Transports the slurried material throughout a hydraulic chamber, where the contaminants become more associated with the solution than the material. The invention then separates the processed material and contaminated solution into unique reclaimed components.
