The effect of electrolysis to recovering tungsten carbide

Recovering of tungsten carbide (WC) with the electrolysis solution in the electrolyte to a reaction with cemented carbide scraps 0.2-1.0 V between temperature from 30-80 C concentration 1-7 N hydrochloric acid solution within 48 hours the results showed the cemented carbide dissolution proper to the influence of voltage temperature and solution concentration. Can recovering tungsten carbide purity over 95.62% of which contain other ingredients include titanium 1.74% tantalum 1.68% and niobium 0.42% concluded that the electrolysis recovering tungsten carbide is appropriate under voltage is 0.4 V temperature 80C 7 N solution of hydrochloric acid recovery rate of tungsten carbide powder about 91.37% with an average particle size of 1.0 m
