<p>The present invention provides a process for stabilizing and consolidating residues based on metal compounds, in particular residues containing jarosites, goethites, iron oxides, iron hydroxides, iron sulfates, in order to allow to store these residues as piles which may be exposed to weather-ing agents, characterized in that said initially free flowing residues comprising at least 55% of solids are mixed with a stabilizing material containing active CaO, in a sufficient amount to form a solid product which is mechanically stable and substantially insensible to the solubilizing action of water, allowing without pollution risk to store this product as weathering exposed piles.</p> |
