Title: STUDY ON MAIN MICROBE GROUP IN SUPERGENE ZONES OF GOLD-CONTAINING GEOLOGIC BODIES
Abstract: It was found that there are different microbe groups in different types of gold ore after the study of the distribution and microbial ecosystem of main microbe groups in 16 gold-containing mining districts. It is apparently different that the distribution of autotrophic sulphur bacteria and heterotrophic bacteria in the gold ore and in the acid mine water. There are more autotrophic bacteria in the acid mine water, but generally more heterophic bacteria in the oxidization zone of gold ore bodies. The dominant bacteria in the oxidization zone of gold ore bodies are mainly the Bacillus cereus of the genus Bacillus. The present paper reveals that main microbe groups in different gold ore bodies have particular significance to expound the formation and diagenesis and alteration of supergene gold ore, and have also the importance to find the bacterium resources for biological wet metallurgy.
