Possibilities of metal recovery from sediment from sludge disposal site

Popis výsledku v původním jazyce

The paper deals with the possibilities of metal recovery from sediment from sludge disposal site after mining activity from locality Zlaté hory. The locality is protected from mineralized water, which represents a potential threat for groundwater. This work deals with the use of bacteria Acidithiobacillus ferrooxidans to bioleach polymetallic ores (Cu, Zn, and Fe) from these locality. It is a simple and effective method to recover metals from mineral raw materials, where conventional methods cannot be applied. As for geology, Zlaté Hory is a highly varied locality with frequent, quartz, muscovite, albinite as well as deposits of sulphide ores (pyrite, chalcopyrite, sphalerite). Leaching lasted for 5 weeks in a bioreactor that ensured optimal conditions for bioleaching. For the bioleaching process, we prepared 9K medium according to Silverman and Lundgren. The leaching process took place in New Brunswick BIOFLO&amp;CELLINGEN 310. Having sterilized the bioreactor, 500 g of sample from Zlatý Chlum at 100% grain size under 0.063 mm. In the course of leaching, samples were drawn after the 1st, 2nd, 3rd, 4th and 5th week. All the samples were washed in 0.1.mol HCl and later in distilled water to stabilize pH. The drawn samples were analysed using a portable spectrometer Dynamic XRF DELTA PROFESSIONAL by BAS Rudice s.r.o. The results imply that the experiments were successful, leaching 54% of Fe, 47% of Zn and 4% of Cu.
