Process Plant Design Considerations for High Silver Gold Ores

Process Plant Design Considerations for High Silver Gold Ores

Acid mine drainage occurs due to the chemical and microbiological oxidation of sulfide minerals and can be a source of potentially toxic elements contamination of groundwater and surface water. The objective of this study was to identify microorganisms involved in sulfide oxidation in the tailings of a Bahia Belt mine Brazil. Samples of solids and water were collected at the mine
