Description

Technical Field

[0001] The utility model relates to the technical field of rare earth ore development, in particular to an ion adsorption type rare earth sample soaking and extraction experimental device. Background Art

[0002] As we all know, ion-adsorption rare earth ore is a special type of rare earth deposit, which refers to rare earth resources in which rare earth ions are adsorbed on minerals in the form of ions. It is a special type of clay mineral formed by long-term weathering of rare earth-containing granite or volcanic rocks. In this process, rare earth ions are adsorbed by hydrated ions or hydroxyl hydrated ions and reside on the surface of clay minerals.

[0003] Before the development of rare earths, it is usually necessary to extract rare earth samples and conduct extraction experiments to determine the rare earth content in the rare earth samples, so as to determine whether there is development value. The extraction of rare earths usually involves first soaking the rare earth ore in an acid solution pool, discharging the leaching solution through the filter layer at the bottom of the pool, precipitating the leaching solution in a saturated oxalic acid solution, and then filtering. The filter cake after filtration is rare earth oxalate, which is calcined, washed with water, and then calcined to obtain a mixed rare earth oxide. Upon searching, patent authorization announcement No. CN 207699648 U discloses a precise extraction device for rare earth ores, "whose structure includes a motor, a reducer, a connector, an extraction device, screws, a water inlet, a fixing bar, a mineral outlet, a sewage hopper, and a feed port". However, the rare earth extraction device crushes the rare earth ores by stirring, but some rare earth ores with higher structural strength cannot be effectively crushed by stirring, so the rare earth ores crushing effect of the above device is poor.
