A kind of rare earth extraction composite material, preparation method and application

Abstract

The present invention provides a kind of preparation method of rare earth extraction composite material, at first manganese sulfate solution and sodium hydroxide solution are mixed, slowly add (NH 4 ) 2 S 2 o 8 Aqueous solution, add zirconia powder and stir evenly, let stand, centrifuge, and dry to obtain manganese-zirconium compound; mix manganese-zirconium compound with 3-phenoxypropionic acid to obtain 3-phenoxypropionate manganese-zirconium compound compound ; Triethylenetetramine and N-n-butyl diacetimide are mixed and stirred to obtain modified N-n-butyl diacetimide; The manganese-zirconium oxypropionate compound compound is mixed and stirred evenly to form a target product rare earth extraction material; the invention also provides the application of the rare earth extraction compound material in the field of rare earth extraction. The invention has simple process, low production cost, can effectively improve the extraction rate, further improves the resource utilization rate in the rare earth extraction process, is simple to operate, has strong practicability, is suitable for industrial production, and can be widely used in the field of rare earth element extraction.

Description

technical field [0001] The invention belongs to the technical field of rare earth extraction materials, and in particular relates to a rare earth extraction composite material, a preparation method and an application. Background technique [0002] Rare earth elements, also known as rare earth metals, refer to the general term for 17 metal elements including lanthanides, scandium and yttrium. It is an important, non-renewable, scarce strategic resource, especially an important raw material for high-tech industries, and has been widely used in electronics, petrochemicals, metallurgy, machinery, energy, light industry, environmental protection, agriculture and other fields. my country is the country with the largest reserves of rare earth resources in the world. The application of rare earth elements in various fields is becoming more and more extensive. However, because the properties of different rare earth elements are very similar, the separation efficiency of rare earth el...
