| titleOfInvention | Method of extracting rhenium from acidic solutions |
| abstract | FIELD: chemistry. n SUBSTANCE: method includes precipitation of rhenium sulfides by processing with sulfide-containing precipitator in presence of reducing reagent in form of hydrazine-containing compound and heating reaction mixture. Precipitation of rhenium sulfides in carried out from hydrochloric acid solution, containing iron chloride. First, hydrazine-containing compound in form of hydrazine chloride, hydrazine sulfate or hydrazine hydrate is introduced into solution in amount 2-4 g/l counted for pure hydrazine. After that, reaction mixture is heated at temperature 60-90°C for 20-40 minutes. Then, counted mass of sulfide-containing reagent is introduced and pulp is heated at specified temperature. n EFFECT: reduction of consumption of reducing reagent and high extraction of rhenium into sulfide sediment from hydrochloric solutions, containing iron salts. n 1 tbl, 1 ex |
