Problems solved by technology

[0004] Based on this, it is necessary to address the above problems and propose a method that can automatically spray the leaching aid onto the ion-adsorbing rare earth ore leaching slag to improve the leaching efficiency of the subsequent ion-adsorbing rare earth ore leaching slag and recover the dropped leaching slag. The ion-adsorbing rare earth ore recovery device that can reduce the loss of ion-adsorbing rare earth ores can solve the above-mentioned background technology. The problem of the loss of permanent rare earth mines

Abstract

The invention relates to the field of rare earth ore, in particular to an ion adsorption rare earth ore recovery device capable of reducing rare earth loss. The ion adsorption rare earth ore recovery device comprises a guide rail plate, grooving guide strips, a leaching residue squeezing assembly, an extrusion liquid collecting assembly and the like, the grooving guide strips are symmetrically connected to the guide rail plate, the leaching residue squeezing assembly is arranged on the guide rail plate, and the extrusion liquid collecting assembly is arranged on the grooving guide strips. By means of a cleaning scraper, redundant ion-adsorption rare earth ore leaching residues on a filter screen can be scraped to conveying belts of other conveying equipment through the cleaning scraper, so that waste of the ion-adsorption rare earth ore leaching residues can be avoided, then the loss of ion-adsorption rare earth ore can be reduced, and the effect of effectively reducing the loss of the ion adsorption rare earth ore is achieved.

Description

technical field [0001] The invention relates to the field of rare earth ores, in particular to an ion-adsorbing rare earth ore recovery device capable of reducing rare earth loss. Background technique [0002] Ion-adsorption rare earth ore, also known as weathering crust elution-type rare earth ore, is a new rare earth mineral that is only used in my country's industry. Because ion-adsorption rare earth ore contains high medium and heavy rare earths and is easy to smelt, it has a strong international market Competitiveness, ion-adsorption rare earth ores are clay minerals formed by weathering of granite and volcanic rocks rich in rare earth minerals and rare earth accessory minerals. The dissociated rare earth ions are adsorbed on the clay minerals as hydrated ions or hydroxyl hydrated ions, and the adsorption Rare earth ions on clay minerals are neither dissolved nor hydrolyzed in water, but they follow the law of ion exchange, so rare earths can be extracted chemically.
