hydraulic washing is the process of washing ore with steam water to remove the lighter impurities whereas liquation is a method of refining in metals with low melting point such as tin and lead are extracted .
In order to determine the optimum washing reagents and their concentrations for extracting arsenic and heavy metals from contaminated mine tailings, soil washing ex-periments were conducted at various concentrations. The concentrations of each washing reagent, except ammonium oxalate, were set to 0.25 M, 0.5 M, and 1.0 M. Due to the low
Extraction of heavy metals from contaminated soil is a process that is highly controlled by the dissolution of the metal–mineral bond followed by the dispersion of the pollutant metal in the washing liquid as an emulsion, complex, or suspension.

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.
