With increasing impurity contents in concentrates, the control of the minor elements is an important issue for the oxygen bottom blown copper smelting process (Shuikoushan process or SKS process). Copper slag, a by-product of copper pyrometallurgy, inevitably contains a certain amount of copper. Oxygen-enriched smelting technologies increase the copper content in slag indirectly because of the production of higher-grade matte.

Copper Mining and Processing: Processing Copper Ores
1 天前Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and Copper matte converting is the key step to ensure high primary copper recovery in the smelting chain. Its development and the fundamental research carried out over the past decades will be reviewed.

Study of Industrial Copper Matte Converting Using
The converting of copper matte after the smelting process is one of the main steps in the copper-making industry. This work used microstructural analyses of samples collected at different stages of converting and thermochemical calculations to study a real converting batch in a Peirce-Smith converter at Atlantic Copper. The transformation of Copper losses during the Peirce-Smith converter (PSC) operation is of great concern in the copper smelting process. Two primary objectives of the PSC are to produce blister copper with a shorter batch time and to keep the copper losses at a minimum level. Due to the nature of the process, those two objectives are contradictory to each Optimal Scheduling of the Peirce-Smith Converter in the Copper

Physicochemical Properties of the Molten Iron-Rich Slags
Molten slag is the main byproduct of the copper smelting industries. Copper slag contains a significant amount of useful metals, such as Cu, Fe, Co and Ni, which are important secondary resources.[1,2,3,4,5,6,7] These elements mainly exist as oxides and matte in the magnetite or fayalite through chemical dissolution and 3.1 Phase Diagram Analysis of the Slag. FeO, SiO 2, and Fe 3 O 4 are the main phases of the copper slag based on the chemical analysis. The FeO-SiO 2-Fe 3 O 4 ternary phase diagram was selected to analyze the position of the slag component in the phase region, as shown in Fig. 3a.

Recovery of Precious Metals (Au, Ag, Pt, and Pd) from Urban
With the aim of investigating deportments of precious metals in pyrometallurgical processing of waste electrical and electronic equipment, the distributions of selected precious metals (gold, silver, platinum, and palladium) between copper matte and three different silica-saturated slags (pure FeOx-SiO2, FeOx-SiO2-Al2O3, and FeOx Practically the matte grade, is adjusted by the ratio of O 2 in the blast and concentrate feed rate, assuming constant slag composition with constant Fe/SiO 2 ratio and oxygen enrichment of the blast. For the reason that the matte grade determines the extent of oxidation of Fe and S in copper smelting, it also determines SO 2 evolution [] and it Thermodynamic Consideration of Copper Matte Smelting
