“…Since 2001, controlled flooding of the mine has been implemented for remediation purposes [1]. Due to the leaching process the flooding water is characterized by a low pH of 2.9 and high concentrations of uranium (13 mg/L) and other heavy metals [2]. Because of the potential risk of uranium mobilization from the flooding waters into neighboring aquifers, particularly the aquifer utilized by the nearby city of Pirna, only half of the mine has been flooded.…”

“…AMD waters are characterized by high sulfate concentrations and high metal content at low pH values. Despite the fact that it is known to be toxic to aquatic organisms [4], [5], uranium plays a major role in the ecosystem of the Königstein flooding water [2]. In bulk solutions, uranium predominantly occurs as aqueous species, such as highly mobile UO 2 SO 4 -species that has been identified in the AMD flooding water [2].…”

It is an important task to remove the uranium and further associated toxic metals from AMD waters to prevent environmental pollution.…”

“…It distributes widely around the world, like USA [1], South Africa [2], Australia [3], Ireland [4] and China [5]. AMD is characterized by the low pH values [1,6], the high iron concentrations and various heavy metal (such as As, Hg, Sb) [7][8]. Iron species and content can affect transport and transformation of heavy metal.…”

The high concentration of ferric (Fe 3+ ) in sample has interference on the determination of ferrous(Fe 2+ ) concentration by spectrophotometric method which 1, 10-phenanthroline is used to as chromogenic agent. Appropriate concentration of fluorine ion (F -) can complex Fe 3+ to eliminate interferences which the F -concentration is 13.3 time greater than that of Fe 3+ . The temperature and light do not affect the masking action of F -. Low temperature and dark conditions favour the stability of chromophoric complex. This method is suitable for determination iron species in the presence of high concentration of Fe 3+ in sample.

“…These voids can be carved in carbonate rocks, but can often be hosted in different geological materials, such as volcanic rocks (Tuccimei et al, 2006), granites, or any other type of solid rock. Only few data were published on Acid Mine Drainage (AMD) environments in which minothems mainly occur as Fe-rich minerals (Campbell & Barton, 1996;Jebrak et al, 1996;Banfield et al, 2000;Nordstrom et al, 2000;Onac et al, 2013;Peterson, 2003;Jamieson et al, 2005;Cabała & Bzowska, 2008;Arnold et al, 2011;Ara et al, 2013). In this case also the term "siderothems" has been used, but minothems should be preferred being a more general term regardless of their chemistry.…”

Abstract:The aim of this study is to characterize in detail, the mineralogy of different-shaped concretions as well as to investigate the physico-chemical parameters of the associated mine drainage and drip waters in the Santa Barbara level of the Libiola Mine (NW Italy) by several geochemical and mineralogical techniques. Under the term "minothems" we are grouping all those secondary minerals that occur under certain form or shape related to the conditions under which they formed but occur in a mine, or in any artificial underground environment (i.e., "mine speleothems"). Different types of minothems (soda straw stalactites, stalactites, and draperies) were sampled and analyzed. Mineralogical results showed that all the samples of stalactites, stalagmite and draperies are characterized by poorly crystalline goethite. There are significant differences either in their texture and chemistry. Stalactites are enriched in Zn, Cd, and Co in respect to other minothems and show botryoidal textures; some of these exhibit a concentric layering marked by the alternation of botryoidal and fibrous-radiating textures; the draperies are enriched in V and show aggregates of sub-spheroidal goethite forming compact mosaic textures. Geochemical investigations show that the composition and physico-chemical parameters of mine drainage and drip waters are different from the other acidic mine water occurrences in different areas of the Libiola Mine, where minothems are less abundant. All mine water samples contain Cu, Ni, and Zn in appreciable levels, and the physico-chemical conditions are consistent with the stability of ferrihydrite, which however tends to transform into goethite upon ageing.
