Manganese deposits in the Early Carboniferous Baping Formation of central Guangxi, South China were formed Youjiang Basin on southern passive margin Block. Hosted Second Member Formation, manganese ore layers interbedded by thin-middle carbonate and silicified carbonate. Previous studies provide limited information about this deposit, sedimentary characteristics ores metallogenic mechanism are ...

The increasing demand of manganese in the industries and various hindrances its production from low grade ores by conventional method has made it imperative for researchers around world to develop a extraction that is both environment-friendly economical. Bioleaching shown significant potential efficiencies have been found be 70–98% with help bacteria fungi. This study focuses on mixed bacteria...

reservas, similares procesos metalogenéticos habrian actuado en el Paleozoico Inferior del Brea. La deformación y el metamorfisme regional hercinicos no han actuado en este sector como un importante reconcentrador de menas, y la mayor parte de indicios epigenéticos Many mineralizations, showings and geochemical anomalies de edad tardihercinicaestán relacionados alas células hidrotermales have b...

Recovery of manganese from ores was investigated by reductive leaching method using reeds as a reductant in the sulfuric acid medium. Cellulose, hemicellulose, and lignin are natural reducing agents which widely used to recover manganese. Effects calcination temperature holding time on efficiency impurities were examined. The have significant effect extraction experimental results demonstrated ...
