摘要：
The investigation focuses on the recovery of silver from hydrometallurgical leach residues of lead-zinc sulfide concentrates using non-cyanide reagents - sodium thiosulfate and potassium thiocyanate. The adsorption of silver from these leach solutions was carried out with a number of anion exchangers and carbon adsorbents, distinguished from each other by their physical structure and functional groups. It is shown that the strong base anion exchanger AV-17-10P and the carbon adsorbent LK-4 based on anthracite, possess the best sorption properties and can be recommended for hydrometallurgical processing.
