Zinc residues, produced from roasting products leaching, containing up to 10 g/t of gold and uprnto 200-250 g/t of silver, go into processing by different methods for recovery of zinc from thesernresidues. Herewith, gold and silver are wasted with copper or iron middling products from processing.rnGold and silver are contained in zinc residue in liberated state as 13-15 % and 12-20 %, respectively.rnBasic amount of precious metals are accreted in minerals and rocks. When flotation dressing of zincrnresidues was used, maximum recovery of silver into silver-bearing flotation concentrate was 70-80%,rngold - 16-20%. When hydrometallurgical processing of zinc residues was used, gold recovery intorncathode settlement, produced from electrolytic processing of thiocarbamide leaching solutions, was 85-rn90 %, silver – 75-80 %.
