Device and method for dispersing two solutions in each other in solvent extraction

摘要

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.

1. A mixing device for mixing two solutions in solvent extraction used in the hydrometallurgical recovery of metals in the mixing space of an extraction cell or mixer, characterised in that the mixing device includes at least three helical bars supported around a shaft and rising upwards from the bottom section of the mixing device, whereby the helical bars are fixed to the shaft with support rings placed horizontally and horizontal curved support spokes, where the support spokes are fixed to the shaft at the first end and to a support ring at the second end.
