Extraction method of gold from electrolyte for electropolishing of products |
| abstract |
FIELD: metallurgy. ^ SUBSTANCE: invention relates to extraction method of gold from ferrostan electrolyte for electropolishing of products, containing complex compound gold ion with thiourea. Method includes destruction of complex by means of treatment of electrolyte 33.0-67.5% solution of hydrogen peroxide. Treatment is implemented at concentration of sulfuric acid, equal to 0.19-0.45 mole/l, with restoration of gold up to the metal. ^ EFFECT: increasing of gold extraction ratio of high grade and process simplification. ^ 1 tbl, 2 ex |
