Recovery device and method for recovering rare-earth metal from rare-earth metal slag

Abstract

The invention discloses a recovery device and method for recovering rare-earth metal from rare-earth metal slag, and belongs to the technical field of rare-earth metal. The recovery device comprises a treatment box, wherein a calcining chamber is arranged on the front surface of the treatment box; an electrolysis tank is arranged on the lower surface of the calcining chamber; and a first driving assembly is arranged on the right side surface of the treatment box, and the lower surface of the first driving assembly is fixedly connected with the upper surface of a fixing block. According to the recovery device disclosed by the invention, crushed materials are fully ground and processed, the materials are ground into fine particles by a sieve plate, the materials containing metal materials can be adsorbed by an electromagnetic plate, and other materials can fall to the inner bottom of the treatment box through discharge holes in the electromagnetic plate, so that automatic feeding is achieved; and meanwhile, the ground and processed materials are effectively sorted, so that the impurity content of the rare-earth metal materials is reduced, subsequent calcination and electrolytic machining are facilitated, the machining efficiency is improved, meanwhile, the quality of recycled rare-earth metal is improved, and the recovery device is quite applicable.

Description

technical field [0001] The invention belongs to the technical field of rare earth metals, in particular to a recovery device and a recovery method for recovering rare earth metals from rare earth metal slag. Background technique [0002] Rare earth metals, also known as rare earth elements, is the general term for the 17 elements of scandium, yttrium, and lanthanide in group IIIB of the periodic table of elements. It is often represented by R or RE. From the discovery of the first rare earth element yttrium in 1794 to the discovery of natural rare earths in 1972 It took 178 years for the element promethium to find all 17 rare earth elements in nature. The luster of rare earth metals is between silver and iron. The chemical activity of rare earth metals is very strong. Because scandium and yttrium often co-exist with lanthanide elements in ore deposits and have similar chemical properties, they are considered rare earth elements. Different from the hint, the abundance of rar...
