Influence of Organic Carbon Source on Biooxidation of Sulfide Concentrate
Abstract—
The goal of the present work was to determine the effect of different concentrations of an organic carbon source (molasses) on the biooxidation of gold-bearing pyrite−arsenopyrite flotation concentrate, as well as on the composition of microbial populations that formed during the biooxidation process. Biooxidation activity increased with increasing molasses concentration in the medium. Concentration of molasses had a greater effect on the total number of microorganisms, while the relative numbers of microorganisms of different groups did not differ significantly. Thus, it was shown that the use of cheap organic substrates is promising to increase the efficiency of biohydrometallurgical processes.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
