摘要： The invention relates to a method for recirculating the heavier solution from the separation part of liquid-liquid extraction to the mixing unit of the same extraction step, so that part of the recirculated solution is returned to the mixing unit from the overflow of the discharge end of the separation part. An essential feature of the invention is that the major part of the heavier solution recirculated into the mixing unit is obtained from the separation part proper, along the whole width thereof. The invention also relates to an apparatus based on said method, in which apparatus, in the bottom part of the settler (6) there is located a heavier solution collecting channel (13) extending over the whole width of the settler and being provided with suction pipes (15) which are oriented in an inclined fashion towards the solution to be collected from the channel.

摘要： The invention relates to a method for adjusting the boundary surface between the two mutually separable solutions in liquid-liquid extraction at the discharge end of the separation part and for preventing the aeration of the solutions when discharging them from the separation part, so that the overflow height of the settled, lighter organic solution is maintained constant. In order to adjust the boundary surface in between the mutually separable solutions, the overflow height of the heavier aqueous solution is adjusted by conducting the settled aqueous solution from down upwards through tubular elements, in which case the height of these overflow pipes can be adjusted. The aeration of the solutions when discharging them from the separation part is prevented by conducting the solutions into transfer pipes through covered, shaft-like weir boxes that are deeper than the discharge end. The invention also relates to an apparatus whereby the boundary surface between the solutions is adjusted and the areation prevented.

摘要： The invention relates to a method for settling the dispersion formed in the mixing unit of liquid-liquid extraction, for controlling solution flows and for creating pure solutions in the separation part. According to the method, the flow speed of the organic solution phase is adjusted to be clearly higher than the flow speed of the aqueous solution phase, in which case in order to prevent border flow turbulence caused by the speed difference of the solution phases, the water drop dispersion layer left in between the separating solutions is adjusted to extend as far as the discharge end of the separation part. In order to settle the solution phases, at the front end of the separation part there are arranged at least three spots where the dispersion and the already settled solutions are made to flow through a picket fence forming a restricted transversal surface, in which case the first restricted transversal surface turns the flow fed into the separation part to follow the longitudinal direction of the separation part, and the second picket fence in the flow direction forming a restricted transversal surface allows the settled aqueous solution phase to flow freely in the bottom part of the separation part. The invention also relates to an extraction apparatus according to the method.
