Bioleaching of Platinum from Tailings in the Krušné Hory Mountains
Original language description
This study explores the bioleaching of platinum group metals (PGMs) from polymetallic sulfide ores using the bacterium Acidithiobacillus ferrooxidans. Samples from two mining sites, Mikulov and Lehnschafter, were subjected to bioleaching experiments in the presence and absence of catalytic additives. Copper sulfate (CuSO4) and silver nitrate (AgNO3) were tested as catalysts to enhance platinum recovery. X-ray fluorescence spectroscopy (XRF) was employed to monitor the platinum content over a 28-day period. The results demonstrated that Cu2+ ions significantly accelerated platinum dissolution, leading to a reduction in platinum concentration from 3549 mg/kg to zero in the Lehns sample. In contrast, the addition of Ag+ ions showed no significant effect. This research underscores the potential of biotechnological methods, specifically bacterial leaching, as an eco-friendly and efficient approach for extracting platinum group metals from ore, especially with the aid of catalytic agents like copper.
