ACID TREATMENT AT LOW TEMPERATURE AND PRESSURE OF WASTE CONTAINING ASBESTOS

摘要

The present invention relates to a method of treating waste containing asbestos, comprising a step (E) in which the asbestos contained in said waste is dissolved by reacting said waste with an acid other than hydrofluoric acid, preferably with hydrochloric acid, at a temperature of at least 125 degrees C and at a pressure greater than 0.2 MPa (2 bar), the solution obtained being valuable, especially for the synthesis of apatites.
