Description

Technical Field

[0001] The present invention relates to the technical field of separation devices, and more specifically, it relates to a cobalt-lithium extraction and separation device. Background Art

[0002] The main components of lithium-ion batteries include a casing, electrolyte, anode material, cathode material, adhesive, copper foil, and aluminum foil, etc. Among them, the mass fractions of Co, Li, and Ni are 5% - 15%, 2% - 7%, and 0.5% - 2% respectively, and there are also metal elements such as Al, Cu, and Fe; from the perspective of the value proportion of the main components, the anode material and the cathode material account for about 33% and 10% respectively, the electrolyte and the separator account for about 12% and 30% respectively. Lithium-ion batteries with LiCoO2 as the cathode material are widely used, which contain chemical substances such as lithium cobaltate, lithium hexafluorophosphate, organic carbonates, carbon materials, copper, and aluminum. The solvent extraction method is a widely used process for the separation and recovery of metal elements from waste lithium batteries. Its principle is to use an organic solvent to form a stable complex with the target ions in the leaching solution, and then use an appropriate extractant to separate it, so as to extract the target metal and its compounds.

[0003] Currently, the main existing extraction and separation method is to fully mix the organic solvent with the leaching solution to form a stable complex between the organic solvent and the target ions in the leaching solution, and then add an extractant and stir it fully to separate the target metal from it. After standing and separating the layers, the target metal is extracted. However, during the stirring process, the mixing effect on a single layer is good, but the mixing effect between the upper layer and the lower layer is poor, thus affecting the extraction of the target metal in the later stage.
