This project aims to investigate mechanisms of copper loss during smelting and find new ways to reduce the loss. Smelting, which produces copper matte product and slag tailings, is an important step of the copper-making process from copper sulphides. The loss of copper to slag can be as high as 12 per cent. The project aims to create new knowledge about copper loss by matte droplets floated with gas bubbles generated by chemical reactions to the slag phase. The outcomes are intended to enable copper smelters to maximise direct copper recovery, reduce copper production costs and increase the productivity of the smelting process.

本项目旨在研究冶炼过程中铜损失的机理，寻找降低铜损失的新途径。冶炼是硫化铜冶炼工艺的重要环节，生产冰铜产品和炉渣尾矿。炉渣中的铜损失可高达12%。该项目旨在创造有关铜损失的新知识，这些铜损失是通过与渣相化学反应产生的气泡漂浮的冰铜液滴来实现的。这些成果旨在使铜冶炼厂能够最大限度地提高铜的直接回收率，降低铜的生产成本并提高冶炼过程的生产率。
