[0002] Rare earth is a general term for 17 metal elements in the periodic table, including lanthanide elements, scandium and yttrium. At present, there are 250 kinds of rare earth minerals in nature. Rare earth itself is relatively rare and therefore its price is quite expensive. Even though my country accounts for 80% of the rare earth production, only some high-tech enterprises and laboratories can buy it. This is enough to prove the preciousness of rare earth.

[0003] In the existing rare earth production and processing process, in order to further improve the utilization rate of rare earth products, it is necessary to recycle rare earth waste for secondary use. When recycling rare earth waste, it is usually necessary to pour a certain amount of acid leaching solution into the rare earth waste so that the rare earth can be dissolved. However, during the treatment process, the two substances are usually not mixed, but the acid leaching solution is directly poured into the rare earth waste treatment frame, so that the rare earth waste and the acid leaching solution cannot be fully contacted, resulting in a slow dissolution rate and low work efficiency. Therefore, it is urgent to design a rare earth waste slag dissolution and recovery device with a high recycling rate. Utility Model Content
