Repeated ultrasonic radiation effects on sulfur oxidation with mixed culture of acidophilic chemolithotrophic microorganisms

Authors: Kioresku A V

High-grade and easy ore resources are being dramatically depleted on a global scale by now. For this reason, it is expected to see an increasing interest in the combined biologicaland-chemical leaching (BCL) applicable to processing of low-grade minerals: tailings, rebellious ore with low content of valuable components. An essential disadvantage of this technology consists in the inability of microorganisms to create an aggressive environment for efficient decomposition of mineral aggregates, which adversely affects duration of processing. This article describes the experiment aimed to study the influence of different-duration repeated ultrasonic radiation on sulfur oxidation efficiency and on the change in the number of free-floating acidophilic chemolithotrophic microorganisms used in BCL technologies. The ultrasonic treatment, subject to the radiation duration, favored the change in such parameters as the number of microorganisms and the medium pH. The number of active plankton bacteria increased in a different degree as compared with the reference quantity subject to duration and mode of radiation. The radiation effect on sulfur oxidation was observed in all test groups and reached maximum by the end of the experiment.

Keywords: bioleaching, sulfur, acidophilic chemolithotrophic microorganisms, ultrasound, tailings, rebellious ore, pH, oxidation, passivation layer.
