中文摘要 | 碳化鎢廢料為鎢和鈷等戰略性金屬的重要資源,其回收技術深受工業化國家之重視。電解法回收碳化鎢不需高溫及真空之設備,可簡化回收流程,減少工業污染,因此甚具發展潛力。本文作者根據往昔電解回收法之缺點,已開發出電解品回收的專利製程技術。本論文之內容在對此一嶄新流程,以電化學熱力學及動力學的觀點進行討論,探討相關的反應機制,以促進其學理上的瞭解和工程上的應用。 |
英文摘要 | Scraps of cemented tungsten carbide were collected to recover the tungsten and cobalt in light of their strategic importance. Electrochemical recovery is a potential technique due to lower consumption of energy and less impact to environmental pollution. Based on electrochemical thermodynamics and kinetics, a patent process involving selective electrolysis has been developed to enhance the reaction rate of reclamation. Subsequently, the recovery mechanism is discussed and a practical flowsheet is proposed. |
