Enhancing Direct Cu Recovery through Increased Gas Processing Understanding

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。渣中的铜损失可高达12%，该项目旨在创造关于铜损失的新知识，即通过渣相化学反应产生的气泡漂浮在冰铜液滴上。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。

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.
