This article provides a scientific analysis of the extraction of bismuth (Bi) from both natural and technogenic sources. The study focuses on the Ustarasoy deposit in Tashkent region and the lead–bismuth sludge generated at the Almalyk Mining and Metallurgical Complex (AMMC). The Ustarasoy deposit represents a bismuth–arsenopyrite hydrothermal vein–metasomatic formation type occurring within Upper Devonian carbonate–aleurolite rocks and hosts minerals such as bismuthinite, kobellite, cosalite, bismutotintinite, and others. The lead–bismuth sludge produced during copper smelting at AMMC contains up to 0.19–2.0% Bi, while converter dust samples contain 0.5–1.0% Bi. Experiments using NaCl solutions to dissolve PbSO₄ revealed that at 95 °C and 300 g/l concentration, the dissolution efficiency of lead reached 85.3%. Simultaneously, the bismuth concentration in solid residues doubled, and enrichment of precious metals (Au, Ag) was observed. These results demonstrate that chloride-leaching technology is a promising method for the recovery of valuable metals from secondary raw materials. The findings form a scientific basis for developing efficient recycling technologies for bismuth and associated metals from industrial wastes.
