I am a PhD student in the Division of Resource Recovery at KTH Royal Institute of Technology, focusing on the recovery of valuable metals from waste permanent magnets. My research explores green solvent leaching and anti-solvent crystallization to develop efficient and sustainable metal extraction and recycling processes.

Before joining KTH, I obtained my Master’s degree from the University of Chinese Academy of Sciences in 2022, where I focused on recovering valuable metals from spent lithium-ion batteries. My research combined pyrolysis and hydrometallurgical techniques to optimize the extraction of key metals such as lithium, nickel, cobalt, and manganese.

My research interests include:

• Hydrometallurgical leaching – Utilizing green solvents for selective and efficient metal extraction
• Crystallization separation – Optimizing crystallization processes to improve purity and recovery rates
• Pyrolysis techniques – Investigating thermal treatment for metal enrichment and recovery

Through my research, I aim to create environmentally friendly and economically viable solutions for recycling e-waste and contribute to the development of a sustainable circular economy for critical metals.
