Process for recovering tungsten values from alkali solutions |
| abstract |
In a continuous process for producing ammonium tungstate from aqueous alkali metal tungstate solution according to an extraction process, the loaded organic extractant is cleaned after stripping by contacting with activated carbon for improving phase separation and decreasing the concentration of alkali metal. |
