    <ns1:title language="en">Treatment of acid mine drainage (AMD) using the neutralization method</ns1:title>
    <ns1:language>en</ns1:language>
    <ns1:description language="en">Abstract: Acid mine drainage (AMD) causes water systems pollution around the mine, and they require water treatment through active or passive treatment methods. Mine waters contain copper ions sometimes in a considerable concentration usually associated with an equivalent or even a two times higher concentration of Fe2+/Fe3+ ions. The presence of other heavy metal ions (Mn, Cd, Zn, Pb, Ni, etc.) in mine water depends on the mineralization of an ore body but their concentration is much lower than the concentration of copper or iron. Mine waters are, as a rule, acidic with pH value mostly between 2.5 and 4. Neutralization of selected AMD with Ca(OH)2 was done in several stages up to different pH values depending on chemical characterization of neutralized water, and depending on the legislation for surface water. The neutralization procedure is applied by the members of the teams of the project RoRS 337, “ROmania Serbia NETwork for assessing and disseminating the impact of copper mining activities on water quality in the cross-border area” (RoSNET2) and detail information concerning this procedure and field sampling details are available in the knowledge base that is built within the above project and at the url: http://www.elearning-chemistry.ro/rosnet2/knowledge-base/.</ns1:description>
