Enhancing Direct Cu Recovery through Increased Gas Processing Understanding (2016–2019)
Smelting is an important step of the copper-making process from copper sulphides, to produce copper matte
product and slag tailings. The loss of copper to slag can be as high as 12%. This project aims to investigate
mechanisms of the copper loss and establish new ways to reduce the loss. It will create new knowledge about
copper loss by matte droplets floated with gas bubbles generated by chemical reactions to the slag phase. The
outcomes will enable copper smelters to maximise direct copper recovery and increase the productivity of the
smelting process. This project is significant to the copper industry because it will reduce copper production costs
and increase profits of the companies in the globally competitive market.
