Rate of Pyrite Bioleaching by Thiobacillus ferrooxidans: Results of an Interlaboratory Comparison

Olson, Gregory J.

RESUMO

Ten laboratories participated in an interlaboratory comparison of determination of bioleaching rates of a pyrite reference material. A standardized procedure and a single strain of Thiobacillus ferrooxidans were used in this study. The mean rate of bioleaching of the pyrite reference material was 12.4 mg of Fe per liter per h, with a coefficient of variation (percent relative standard deviation) of 32% as determined by eight laboratories. These results show the precision among laboratories of the determination of rates of pyrite bioleaching when a standard test procedure and reference material are used.
