The Cu-As-containing filter cake waste and black copper sludge are the main by-products, besides sulphuric acid and slag, in the copper production. To achieve sustainability in copper making and satisfy more strict environmental requirements, this study discusses the possibility of feeding them back into the smelting step. By collecting samples of filter cake waste and black copper sludge from copper industry, followed by Inductively Coupled Plasma-Atomic Emission Spectroscopy, X-ray Diffractometry and Scanning Electron Microscopy-Energy Dispersive X-ray Spectrometry, the mineralogy, morphologies and compositions of filter cake and black copper sludge were determined. Furthermore, the reaction mechanism of the by-products in FSF was discussed from thermodynamic aspects. Finally, a CFD simulation was conducted on an industrial furnace scale using different copper concentrate/by-product ratios, and the pyrometallurgical recycling of the filter cake waste and black copper sludge were discussed and evaluated.

含铜砷滤饼废液和黑铜泥是铜生产过程中除硫酸和矿渣外的主要副产物。为了实现铜制造的可持续性并满足更严格的环境要求，本研究讨论了将它们送回冶炼步骤的可能性。通过采集铜工业滤饼废料和黑铜泥样品，通过电感耦合等离子体原子发射光谱、X射线衍射和扫描电子显微镜-能量色散X射线光谱分析，对滤饼的矿物学、形貌和成分进行了研究和黑铜污泥被确定。此外，从热力学方面讨论了FSF中副产物的反应机理。最后，
