dc.description.abstract | The potentiostatic mode of anodic dissolution of tungsten carbide-cobalt alloys in phosphoric acid solutions, which makes it possible to selectively dissolve tungsten and cobalt and separate the solid tungsten carbide phase, is experimentally validated and practically implemented. The curves of the rate of dissolution of cobalt and tungsten in the WC-Co (6%) alloy versus die electrode potential and dissolution duration are determined. It is shown that tungsten is extracted from tungsten ores and concentrates in sodium chloride-sodium metasilicate melts into the halide phase at a temperature of 1050 to 1050-1100°C. The compositions of the melts that provide the exfraction efficiency as high as 99% and maximal ratios of separation of the components between the phases are chosen. | uk_UA |
