Abstract
The article explores methods for determining and quantitatively assessing rare and dispersed elements in Kazakhstan’s technogenic waste, particularly metallurgical slags from the Zhezkazgan region. An environmentally friendly and economically viable technology is proposed for direct metal extraction using mechanochemical processes in a planetary mill. The technology is waterless, does not require chemical reagents, and is characterized by high efficiency and low operational costs. Experiments conducted on metal recovery confirmed the method’s high effectiveness. The analysis of recovered concentrates revealed a high yield of valuable elements, demonstrating the feasibility of large-scale implementation. This development addresses both the rational use of mineral resources and the ecological rehabilitation of industrial zones, making it highly relevant for the region’s sustainable development.
