Carbon-in-leach and carbon-in-pulp are continuous processes that use activated carbon in a cascade of large agitated tanks, which have been widely used to recover or concentrate precious metals in gold extraction plants. ...

Biosolids are residues from the treatment of urban fluids used as a source of nutrients for agricultural and forestry crops. The organic matter contained in this residue and its chemical characteristics may interfere with ...

pH-swing mineral carbonation is kinetically favorable and requires a short reaction time. It must also obtain a high extraction rate for reactive elements in the leaching process. The main purpose of this study is to ...

Two acid imidazolium-based Ionic liquids (ILs) were evaluated for use in the leaching of a real non-concentrated chalcopyrite ore in an aerated system at different temperatures, monitoring copper recoveries in aqueous ...
