Equipment for selectively extracting non-cerium rare earth in mixed rare earth concentrate

Abstract

The invention relates to non-cerium rare earth equipment, in particular to equipment for selectively extracting non-cerium rare earth in mixed rare earth concentrate. The invention provides the equipment for selectively extracting the non-cerium rare earth in the mixed rare earth concentrate, and the equipment has the advantages of automatic extraction, good extraction effect and simple and understandable operation. The equipment for selectively extracting the non-cerium rare earth in the mixed rare earth concentrate comprises a first mounting frame, a second mounting frame, a discharging frame, a filtering mechanism, a filtering box and a blocking mechanism, and the second mounting frame is arranged in the middle of the first mounting frame; the discharging frame is arranged between the two sides of the first mounting frame; the filtering mechanism is arranged in the second mounting frame; the filtering box is arranged on the filtering mechanism in a sliding manner; and the top of the second mounting frame is provided with the blocking mechanism. Two first movable rods both move leftwards to be reset, so that the filtering box moves leftwards to be reset, the rare earth concentrate can be filtered and screened through left-right movement of the filtering box, the rare earth concentrate can be extracted, and the filtering effect is achieved.

Description

technical field [0001] The invention relates to equipment for non-cerium rare earths, in particular to equipment for selectively extracting non-cerium rare earths in mixed rare earth concentrates. Background technique [0002] Rare earth ores mainly exist in the form of minerals in the earth's crust. As the basic constituent elements of minerals, rare earths exist in mineral crystals in the form of ionic compounds, which constitute an essential component of minerals. China's rare earth ores are mainly concentrated in Baiyun Obo, Inner Mongolia, North China. The iron region is the main production base of light rare earths in China, and the main part of heavy rare earths is in the southern region. Rare earth ores can be used to manufacture flint, rare earth ductile iron, and petroleum cracking catalysts. Currently, in some rare earth ore extraction plants, usually Rare earth ores are extracted manually using simple tools. This method cannot completely extract rare earth ores, ...

Problems solved by technology

[0005] In order to overcome the shortcomings of artificially using simple tools to extract rare earth ores, this method cannot completely extract rare earth ores, and the extraction effect is not good. The technical problem to be solved is: to provide an automatic extraction, better extraction effect and simple operation. Easy-to-understand equipment for selective extraction of non-cerium rare earths from mixed rare earth concentrates
