Abstract
The invention relates to a method for dispersing the two liquid phases of a solvent extraction process well together, for controlling the desired type of dispersion and for raising the created dispersion to a level essentially higher than the liquid surface in the mixing tank. In the apparatus of the invention, to the circulation cylinder (6) of the mixer there is connected the heavy phase return conduit (27) and the light phase return conduit (29) entering from the settler of the same extraction step. In the top part of the mixer, coaxially with the turbine pump (9), there is installed the dispersion pump (12) where the dispersion rises to above the liquid surface (8) of the mixer through 2-24 rising pipes (15). The top ends of the rising pipes (15) are connected to the circular pipe (18), wherefrom the dispersion flow is conducted to the next stage through the collecting trough (22).

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
