A mixing method and device for solvent extraction, especially in hydrometallurgical processes

摘要

A system and method are disclosed for mixing a suspension. The suspension may optionally have a low liquid viscosity. The suspension may, optionally, include a metallurgy solvent extraction (SX) mixture. The system and method may be at an industrial scale. In some embodiments, suspension may be stirred at high energy dissipation rate with a large impeller. The system may optionally include baffles. The impellor and/or the baffles may optionally include a rounded edge. The method may be applied to retrofitting a SX plant. The input feed to a mixing reactor may include an emulsion and/or multiple discrete phases.
