Characterization and treatment of neutral mine drainage (NMD) from three mines located in the “Colline Metallifere” park near Grosseto (Tuscany, Italy) is the main objective of this research.

Abstract

Characterization and treatment of neutral mine drainage (NMD) from three mines located in the “Colline Metallifere” park near Grosseto (Tuscany, Italy) is the main objective of this research. As a consequence of NMDs characteristics, the first study focused on an ‘active’ coagulation-flocculation-sedimentation process with jar-tests and settleability in column tests. In the second term the objective of laboratory scale trials was the treatment of NMD by slow filtration with several nonwoven fabrics. Finally, exhausted nonwoven fabric were used in slow filtration tests to verify the sorbent potential of metallic (oxy-)hydroxides for As removal from contaminated groundwater.
