Process for the decontamination of mud, in particular sea and lagoon sediment, or earth from organic and/or inorganic micropollutants characterized in that it essentially comprises the following steps:thermal desorption from the mud or earth of organic micropollutants and volatile metals in an oven at a temperature ranging from 300 to 700°C, obtaining a gaseous stream containing the organic pollutants and volatile metals removed and a residual solid stream;extraction of the heavy metals from the residual solid stream by means of inorganic acids or kelating compounds in aqueous solution, in one or more steps, by chemically dissolving said heavy metals, obtaining substantially detoxified mud or earth having such characteristics as to enable it to be replaced in the original site.展开▼
