Description

Technical Field

[0001] The utility model relates to the technical field of lithium extraction from lithium slag, and discloses auxiliary washing equipment for lithium extraction from lithium slag. Background Art

[0002] Lepidolite lithium slag is the waste residue produced in the process of extracting lithium and its compounds from lepidolite ore. It is a solid waste produced by extracting valuable metals using sulfuric acid method, sulfate method, limestone method and salt pressure cooking method. How to scientifically and environmentally friendly comprehensively recycle and utilize the valuable metals in lithium slag is becoming increasingly important. At present, the valuable metals in lithium slag are mainly lithium, potassium, rubidium and cesium.

[0003] For example, in the process of extracting lithium using lepidolite as raw material, after lepidolite and sulfate are roasted, that is, the raw material after crushing lepidolite or lithium ore and sulfate are fully mixed, roasted into clinker, leached, and filtered, a filtered lithium slag material is obtained, and this part of the filtered lithium slag material can continue to be used for lithium extraction. First, the filtered slag needs to be further rinsed or washed. If the washing treatment is not good, that is, the rare metal elements such as lithium in the filter slag are not rinsed cleanly, the residual very small amount of lithium, rubidium, cesium and other elements will be discarded with the washing slag, which will also cause the lithium, rubidium, cesium and other important rare metal elements calcined from the lepidolite to be wasted along with the loss of the washed lithium slag, resulting in unnecessary resource loss, and further increasing the production cost of extracting lithium salts from lepidolite.

[0004] In the existing lithium slag washing equipment, after pouring the lithium slag into the washing tank, the lithium slag is not stirred, resulting in insufficient mixing of the lithium slag and the washing solution, which in turn causes a large amount of waste matter to remain on the lithium slag, easily affecting the washing effect.

[0005] Therefore, there is a need for an auxiliary washing device for lithium slag extraction that can stir the lithium slag to solve the problems existing in the prior art. Utility Model Content
