摘要：

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.
