Method for separating rhenium from solutions containing perrhenic acid |
| abstract |
PROBLEM TO BE SOLVED: To provide a low-cost method capable of separating rhenium stably and efficiently even when the content of rhenium in a raw material varies greatly. A method for separating rhenium from a solution containing one or more elements of copper, zinc, cadmium, and arsenic and perrhenic acid, wherein an alkali such as sodium hydroxide is added to the solution. A first step 1 for producing a precipitate and solid-liquid separation of the solution containing the precipitate by a separation method such as filtration; and an acid such as sulfuric acid is added to the separated liquid obtained by the solid-liquid separation to obtain an equivalent concentration of 1 Second step 2 for adjusting the acid concentration within the range of 0.0 N or more and 4.0 N or less, and by adding a sulfurizing agent such as sodium hydrogen sulfide to the adjustment liquid obtained by adding the acid, sulfide sulfide is generated. And a third step 3 for separating the sulfide from the liquid after sulfidation. [Selection] Figure 1 |
