Abstract
Bottom blown oxygen copper smelting process, operated at high grade matte (up to 75 wt% Cu) with relatively low (2–3 wt%) Cu in slag, has been commercialized for more than five years at Dongying Fangyuan Nonferrous Metals CO., Ltd. Quenched slag and matte samples have been collected at different operating conditions while the slag temperature was measured by thermocouple. The samples were analysed by X-ray Fluorescence and Electron Probe X-ray Microanalysis. FactSage computational software was used to explain the observations of the industrial samples. The analyses show that the copper loss was closely related to the operation parameters. The Fe/SiO2 in slag and temperature determine the solid proportion, which significantly affects the physical entrained and also chemically dissolved copper in the slag. The present study will be useful in understanding the slag chemistry of bottom blown copper smelting furnace and in optimization of the operating conditions to lower Cu loss in the slag.
