摘要: The authors have been developing the method to recover material of sintered carbide in electrochemical machining (ECM). ECM performance is affected by change electrolyte ingredient when dissolved into electrolyte. Besides, tungsten and cobalt are costly rare metals. In this report, feasibility a process on recovery changing soluble substances insoluble ones was investigated, which as calcium tungstate hydrate. It found that compounds could be recovered proposed processes.
