Attention has been focused in recent decades upon the precipitation of metal sulfides from acid mine drainage (AMD) and pregnant leach solutions, due to the advantages of the sulfide precipitation process over traditional methods employing hydroxides

Manganese is one of the most difficult elements to remove from mine waters, due to its high solubility in both acid and neutral conditions; thus it can be found in quite high concentrations, depending on the rock’s mineralogy. Metal carbonate preci

Limestone can be an option for sulfate sorption, particularly from neutral mine drainages because calcium ions on the solid surface can bind sulfate ions. This work investigated sulfate removal from mine waters through sorption on limestone. Continuo

Fixed-Bed and Stirred-Tank Studies of Manganese Sorption by Calcite Limestone

Autor: Adarlene M. Silva, Fabrício C. M. Cordeiro, Emannoelle C. Cunha, Versiane Albis Leão

Publikováno v: Industrial & Engineering Chemistry Research. :120913092229000

This study addressed manganese removal from mine waters in a stirred tank as well as fixed-bed experiments. Manganese sorption on limestone is described by pseudo first-order kinetics. Equilibrium sorption was modeled by the Langmuir isotherm, and li
