| Abstract Scope |
The copper, zinc, and lead targeted in non-ferrous metal refining have relatively low CO2 emissions in their smelting processes, excluding zinc. From the perspective of global warming, this is not a significant issue. However, special attention must be given to the treatment of environmental regulatory elements such as arsenic (As), cadmium (Cd), and mercury (Hg) due to the handling of heavy metals.
On the other hand, copper is expected to experience increased demand due to the use of renewable energy sources, among other factors. There may be some challenges in the supply of primary resources, which is why recycling is desired.
This presentation provides an overview of the roles of these metals in society, their refining processes, and the future challenges concerning recycling. By showcasing the collaboration between different refining technologies, it demonstrates how they can contribute to reducing environmental burdens and promoting the circular use of various metal materials. |
