In recent years, the demand for rare earth metals has increased significantly worldwide. 6 this is due to the constant increase in their role in the leading sectors on which the economic and defense security of any state depends. In particular, as foreign experience shows, the use of high-quality low-grade niobium and rare earth 6olates will lead to significant results in Mechanical Engineering, Gas and oil industries and their 6-line pipelines, construction of large engineering structures, nuclear power facilities and 6 other major industries. Every 6 tons of niobium added to low carbon 6olates during construction processes saves 200-300 tons of 6olates and reduces the weight of the structure by 30-40%. 6 at the same time, the service life of so-called processes increases by 1.5-2 times. At present, there are no fundamentally new ideas for the selectivity of metal ions from industrial solvents and the creation of new technologies. 6ar development of mole extraction of metal ions mainly involves the use of ion exchange resins. In particular, Kazakhstan uses the extraction and conversion of gold ions (cyanide ions), rare earth metals (nitrates, chlorides) from industrial (industrial) industrial resins of American and French production. However, positive substituents do not have a high degree of metal extraction, and their regeneration is a fairly complex process. In addition, the use of replacement resins is designed to select only 6 metals, and The Associated 6-year-old components are in the composition of the processing solution.
