Jinfeng is investigating processes for resource recovery from municipal solid waste incineration ash. Recovery of e.g. copper, zinc and lead from MSWI ashes will not only recover valuable metals that would otherwise be land filled, but also reduce the toxicity of the ash and thereby make it possible to use a less expensive landfill option or perhaps even to utilize the ash residue as a construction material. The processes are primarily based on acid leaching combined with selective extraction and/or electrolysis to recover valuable metals. Previous work included recovery of metallic magnesium from black dross through vacuum distillation and leaching, which gave Jinfeng the opportunity to continue his research as a PhD student since March, 2012. He has also done some research work focusing on the simulation of metal forming.
