Illinois coal ground to 80-200 mesh was leached
with a low phosphate, high nitrogen medium containing a
mixture of Thiobacillus ferrooxidans and thiooxidans in a
fluidized bed. Coal slurries of 20-160 g/L were treated
in a 5 cm ID, 9.5 m high continuous loop bioreactor with
crossovers at top and...
The bacterium most frequently used in microbial
leaching processes and studies is Thiobacillus
ferrooxidans. Applications of this bacterium include the
treatment of coal, low-grade ores and industrial solid
wastes for the solubilization of pyrite and other trace
metals associated with sulfides. The goal of this study
was the development of...
