The qualitative and quantitative composition of NdFeB magnet has been established, the features of metal leaching by nitric acid solution have been studied. Optimal conditions of the process of the most complete leaching of metals were selected. A hydrophobic deep eutectic solvent based on di(2,4,4-trimethylpentyl)phosphinic acid (DTMPPA) and phenol was proposed as an extractant for the extraction of a series of metals from the nitric acid solution of neodymium magnet leaching. Experimental data on the extraction of Ni, Fe, Al and Cu ions from model individual and mixed solutions by deep eutectic solvent DTMPPA/phenol under varying key conditions of the process: acidity of the medium, concentration of the desalting agent, concentration of components in the eutectic solvent, metal concentration, etc. were obtained. The results obtained indicate the promising application of deep eutectic solvent DTMPPA/phenol for the extraction of Ni, Fe, Al and Cu cations in the processes of waste recycling of magnetic materials.
