A New Method of Tungsten Extraction by Liquid Cathode Molten Salt Electrolysis-Zinc Melt Separation
摘要
This paper describes a new process for the separation and recovery of refractory metal carbides. Zinc was used as the working electrode and collector of the electrolysis products. The electrolysis products were obtained by constant current electrolysis at a temperature of 775 °C. The electrolysis products were then subjected to zinc smelting. The Co–W alloy is removed by static precipitation and high temperature liquid phase separation, and the tungsten is separated and extracted.
