Abstract
The invention relates to a mixing device and method by means of which two solutions that are insoluble or poorly soluble in each other are mixed together into a dispersion. The device consists of at least three helical bars rotating upwards around a shaft and supported on it, so that the support structures between the shaft and the helical rods are set essentially in a horizontal position. The device and method are particularly suitable for mixing solvent extraction solutions used in the hydrometallurgical recovery of metals to form a dispersion.
