摘要 |
FIELD: rare metal metallurgy, possibly extraction of rhenium out of technogenic raw material containing metallic rhenium or its alloys. ^ SUBSTANCE: method comprises steps of chlorinating with chlorine gas at 20°C in liquid medium dimethylformamide and water at mass relation of technogenic raw material: dimethylformamide : water such as 1 : (20 - 25) : (8 - 10) and at relation of technogenic raw material : chlorine such as 1 : (35 - 45). Method is simply realized for one stage without heat supply; it does not need deficient equipment and high-cost reagents. Method allows for one operation provide rhenium extraction degree 25.7% at initial temperature of process 20°C and initial content of rhenium in alloy 42.5%. ^ EFFECT: significantly simplified process of rhenium extraction from waste alloys of special technology branches, lowered energy consumption. ^ 1 tbl, 4 ex |
