MINERALOGY AND GEOCHEMISTRY OF OCHREOUS SEDIMENTS FROM VARIOUS SB DEPOSITS (SLOVAKIA)
Abstract
The objective of our study was to examine the mineralogy and chemical composition of ochreous sediments accumulated in the area of four abandoned Sb deposits from Slovakia. Each of them is from different geological settings and there are also differences between types of mineralization and mine processing. Samples were collected mainly from mine drainages and fraction under 0.063 mm was analyzed using conventional methods, including X-ray diffraction, IR spectroscopy, transmission electron microscopy and sequential extractions. Schwertmannite was identified as predominant mineral phase in acidic conditions, but while carbonates are very common in most of the studied localities, neutral pH prevails and therefore ferrihydrite is precipitating most often. In older sediments ferrihydrite transforms to more stabile goethite. Total content of As is 2128 mg/kg in case of schwertmannite sample and varies from 433 mg/kg to 134 g/kg in ferrihydrite samples; Sb content in schwertmannite is 35 g/kg and in ferrihydrite samples is in range from 893.2 mg/kg to19 g/kg.
