However, the potential release of dissolved metals, acidity, or suspended particulates from mine-waste dumps can be a serious and long-lasting problem. A variety of environmental impacts may occur at this abandoned mine sites and leading the list is acid generation, which is one of the main problems from metal mining. The objective of the present study was to characterize and evaluate the Romanian historical tailing of Sasar-Red Valley, near Baia Mare. This involved physical and chemical characterization of the materials and its acid generating potential. Sasar tailing impoundment contains 8.5 million m\n                    <jats:sup>3<\/jats:sup>\n                    of tailings and occupies an area of 32.5 hectares. Tailings samples were collected from different depths in three sampling points, and characterized by grain size, chemical elements concentration, elements distribution of elements in depth, paste pH, acid-base account and net acid generation tests. Acid base accounting (ABA) tests in conjunction with net acid generation (NAG) tests classified the samples into the category of \u2018potentially acid generating\u2019. This paper presents a synthesis of works performed in the Improve Resource Efficiency and Minimize Environmental Footprint (REMinE) project.\n                  <\/jats:p>","DOI":"10.1051\/e3sconf\/20171801031","type":"journal-article","created":{"date-parts":[[2021,8,13]],"date-time":"2021-08-13T07:07:55Z","timestamp":1628838475000},"page":"01031","source":"Crossref","is-referenced-by-count":1,"title":["Physical chemical characterization of historical mining waste and ARD prediction tests"],"prefix":"10.1051","volume":"18","author":[{"given":"Antoneta","family":"Filcenco-Olteanu","sequence":"first","affiliation":[]},{"given":"Lena","family":"Alakangas","sequence":"additional","affiliation":[]},{"given":"Antoio","family":"Fiuza","sequence":"additional","affiliation":[]},{"given":"Marius","family":"Zlagnean","sequence":"additional","affiliation":[]},{"given":"Nicolae","family":"Tomus","sequence":"additional","affiliation":[]}],"member":"250","published-online":{"date-parts":[[2017,10,4]]},"reference":[{"key":"R1","unstructured":"G.
