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.
