鉄酸化細菌による硫化鉱物の酸化現象

抄録

Thiobacillus ferrooxidans, a chemoautotroph using iron oxidation as an energy source for growth, is attracting the interesti n its role in leaching of sulfide minerals.
Many studies on this bacterium have been performed principally in the ecological aspects for over 30 years since the discovery of it. From the results of these studies, more research works regarding following subjects will be necessary for the further progress of the bacterial leaching.
1) Establishment of the suitable environment for the bacterial action.
2) Discovery of more effbctive species or improvement of strains.
3) Development of effective combination with other unit operationsuch as flotation and agglomeration
