In order to promote the development of a vegetal cover on a dump of mining residues, endogenous plants that started to colonize the waste material were collected and identified. The strategy of remediation included the selection of amendments that could optimally promote plant growth and decrease the mobility and bio-availability of the main toxic elements present in the residue, i.e., arsenic, lead and barium.
