Used automotive catalysts are a valuable source of rare and precious metals, which plays key role in modern industry. These raw materials contain earths makes their processing highly efficient economically profitable. To develop comprehensive technology, were studied using various analysis methods, such as chemical, X-ray, X-ray spectral, electron microscopic analysis. The results the phase indicate that noble metals states, form oxides embedded aluminosilicate matrix catalyst. data critical importance for creation effective methods metal extraction. approaches these pyrometallurgical hydrometallurgical technologies, each has its own advantages unique performance criteria. This article focuses on physico-chemical studies spent proposed method opening, it possible to efficiently extract rare, rare-earth metals. research can be used optimize existing new technological schemes secondary materials.
