Oxidation of pyrite and marcasite by Thiobacillus ferrooxidans bacteria

Nowaczyk K. , Domka F.

nr 2

This paper reports results of studies on the influence of the crystallographic mineral structure on the process of pyrite and marcasite leaching. Kinetic studies show that the crystallographic structure of minerals like FeS2 type does not influence the efficiency of the process.

The aim of this study was to evaluate the effect of additives such as waste moulding sands (WMS) and dolomite flotation waste (F) on heavy metal immobilization during vitrification of tannery sewage sludge. Sewage sludge with addition of waste moulding sands of 25-45 vol. % and flotation waste of 5-25 vol. % was used in the vitrification process. The study demonstrated a direct correlation between the WMS fraction in the vitrified formulations and heavy metal immobilization in the obtained vitrificates. Vitrification of sewage sludge with these additives resulted in obtaining vitreous products with reduced heavy metal leaching properties; the lowest content of heavy metals in the leachates was found in the vitrificates with the highest content of waste moulding sands.

The possibility of utilization wastes resulting from mining and burning lignite using the method of microbiological leaching has been presented. It has been found, that high yield (40-80%) of the recovery of metals (Cu, As, Mn, Ga, Be, V, Ti) in the presence of a mixture of Thiobacillus bacteria: T. ferrooxidans and T. thiooxidans, is possible. The effectiveness of metals leaching (basing on titanium extracted) was high both with autochthonous and museum strains of bacteria used.
