Acid treatment under low temperature and pressure of a waste containing asbestos

摘要

The present invention relates to a process for the treatment of a waste containing asbestos, comprising a step (e) in which there are dissolved, asbestos contained in said waste material by reacting the waste with an acid other than the 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, which can be upgraded, in particular for the synthesis of apatites.
