摘要： The present invention relates to processes for recovering areas degraded by mining by means of soil treatment. In this context, the present invention provides a method for reusing ore concentrate waste, comprising the steps of (i) generating a solid or pasty residue from ore concentration, (ii) enriching the residue with at least two organic binders and a fertilizer to obtain an enriched/improved residue, (iii) depositing the enriched residue on the mined ground to form an enriched subsoil and (iv) depositing a topsoil layer on the enriched subsoil.
