Replacement of refractories due to slag attack is a major cost in the copper making process. Metallurgists need to find a better slag which retains the benefits of current slags but is less aggressive towards refractories. This project will assess the suitability of a newly proposed ferrous calcium silicate slag for continuous copper converting. The outcomes will be to: (1) provide fundamental knowledge of the properties of the SiO2-CaO-FeO slag system, (2) provide data on the rate and mechanism of refractory attack by this slag and (3) enable the copper smelting industry to assess the potential of this slag to reduce operating costs.

由于炉渣侵蚀而更换耐火材料是炼铜过程中的主要成本。冶金学家需要找到一种更好的炉渣，既保留了现有炉渣的优点，又对耐火材料的侵蚀性较小。该项目将评估新提出的铁钙硅酸盐渣用于连续铜吹炼的适用性。 其成果将是：（1）提供SiO2-CaO-FeO渣系性质的基本知识，（2）提供该渣对耐火材料侵蚀的速率和机理的数据，和（3）使铜冶炼工业能够评估该渣降低操作成本的潜力。
