A method for decontaminating soil containing inorganic contaminants having a
degree
of liberation of at least 60%, comprising the steps of removing from a coarse fraction
at least a portion of inorganic contaminants in particulate form contained therein
with a jig to produce a treated coarse fraction, removing from an intermediate
fraction at least a portion of inorganic contaminants in particulate form contained
therein with a separator selected from the group consisting of a spiral and a classifier
to produce a treated intermediate fraction, removing from a fine fraction at least
a portion of inorganic contaminants in particulate form contained therein with
a separator selected from the group consisting of a flotation cell and a multi-gravity
separator to produce a treated fine fraction, whereby the combined treated coarse,
intermediate and fine fractions are impoverished in inorganic contaminants.
