Rare earth recovery system and recovery process thereof

Abstract

The invention discloses a rare earth recovery system. The rare earth recovery system comprises a filter tank, a clear liquid tank, a sedimentation tank and two dissolving tanks, wherein each dissolving tank comprises a filter pressing device and a uniform mixing device which are provided with linkage structures. The invention further discloses a rare earth recovery process using the rare earth recovery system. According to the rare earth recovery system and the rare earth recovery process, the filter pressing structures and the uniform mixing structures in the dissolving tanks are improved, so that the filter pressing structures and the uniform mixing structures can be subjected to linkage operation, the filter pressing efficiency is improved, the filtrate is fully dissolved, and the extraction rate of rare earth ore is improved. The rare earth recovery system is simple in structure, the rare earth recovery process is convenient and fast, large-batch rare earth recovery can be carried out, and manpower and material resources are saved.

Description

technical field

[0001] The invention relates to the technical field of rare earth recovery, in particular to a rare earth recovery system and a recovery process thereof. Background technique

[0002] Rare earth minerals mainly exist in the form of minerals in the earth's crust, and there are three main types: as the basic constituent elements of minerals, rare earths exist in the mineral lattice in the form of ionic compounds, and constitute an essential component of minerals. These minerals are usually called rare earth minerals. Rare earth mineral elements are known as "industrial vitamins". They have irreplaceable excellent magnetic, optical and electrical properties, and play a huge role in improving product performance, increasing product varieties, and increasing production efficiency. . Due to their great effect and low dosage, rare earths have become an important element to improve product structure, increase technological content, and promote technological progress...
