Abstract

The processing of copper–molybdenum concentrator tailings by low-temperature roasting with NaOH, followed by leaching and filtration to produce sodium metasilicate, was studied. The aluminum-enriched concentrate is treated with a dilute HNO₃ solution. The resulting aluminum salt filtrate is processed into alumina or other aluminum compounds using established methods. The remaining solid residue can be used as a raw material for the production of construction materials.
