ABSTRACT:
The invention relates to a method of eliminating mercury or arsenic from a fluid in the presence of a solid mass for the recovery of mercury and/or arsenic. The said mass contains copper and sulphur at least partly in the form of copper sulphide and results (a) from the incorporation of a copper compound other than a sulphide into a solid mineral support, (b) possible calcination of the product obtained in stage (a), and from bringing the product obtained previously into contact with elementary sulphur and (d) a heat treatment.
