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.
