PYROMETALLURGICAL PROCESS FOR TREATING METAL-CONTAINING MATERIALS |
摘要 |
A process for forming a salt, such as sodium tungstate, using a pyrometallurgical operation is provided. A slagging operation is performed in which a metal-containing material is melted in the presence of slag formers such as sodium metasilicate and silica. The metal predominantly reports to a denser metal-containing phase. The denser metal-containing phase may then be subjected to gas sparging with a carbon-containing gas in order to form metal carbide, preferably tungsten carbide.
