ACID TREATMENT, AT LOW TEMPERATURE AND PRESSURE, OF A WASTE CONTAINING ASBESTOS |
摘要 |
The present invention relates to a process for treating a waste containing asbestos, comprising a step (E) in which the asbestos contained in said waste is dissolved by reacting this waste with an acid other than hydrofluoric acid, preferably with hydrochloric acid, at a temperature of at least 125°C and at a pressure greater than 0.2 MPa (2 bar), and in which: the asbestos included in the treated waste is an asbestos of amphibole type; and/or the solution obtained at the end of the acid dissolution of the asbestos is reused, for example for the synthesis of apatites. |
