摘要： The invention relates to a method and apparatus for mixing one or several solutions in a reactor (3) in conjunction with a hydrometallurgical process, such as precipitation, crystallisation or forming a suspension in solvent extraction. Mixing with a vertical circulation flow is created in the reactor by means of a multi-part mixer (1), so that the primary mixing zone in which the mixer rotates is over 70 % of the effective volume of the reactor, whereby the homogenous, low-intensity mixing needed for precipitation, crystallisation and/or the mixing stage of solvent extraction is achieved.

摘要： The invention relates to a method and apparatus with which the aqueous solution from liquid-liquid extraction in the hydrometallurgical recovery of metals is purified from droplets of organic extraction solution. The aqueous solution is treated in a settling tank, where it is made to flow through a flow channel area with a reduced cross-section that extends over the width of the tank at least at one point. The flow channels are located in the lower section of the droplet coalescer according to the invention, with the upper section of the device being mainly solid.

摘要： The invention relates to a method and equipment with which an organic solution extraction solution is purified from entrainment of aqueous solution and impurities during hydrometallurgical liquid-liquid extraction. The method treats an organic extraction solution, which is loaded with a valuable metal or valuable substance from the aqueous solution. The extraction solution is scrubbed with an acidic aqueous solution. The acidic solution is discharged into the tank in several separate sub-streams. The flow diverts from horizontal to vertical and the direction of the separated solutions is deflected by means of picker fences (13, 14). The organic solution and the aqueous solution are removed in separate sub-streams. A settler comprises several discharge elements (12) for organic solution and suction elements (16, 24) for removing organic solution and aqueous solution respectively.
