Abstract The results of an investigation on copper losses in industrial slag from the Teniente converter (TC) and from the electrical slag cleaning furnace (EF) at the Paipote smelter in Chile are presented. Slag samples from each furnace were characterised using chemical and mineralogical techniques. The distribution of the various phases, including entrained matte, was quantified by semi-automatic image analysis. The level of soluble copper was measured by EPMA on samples cooled at a fast… Expand

Minimization of Copper Losses in Copper Smelting Slag During Electric Furnace Treatment
In the quest to achieve the highest metal recovery during the smelting of copper concentrates, this study has evaluated the minimum level of soluble copper in iron-silicate slags. The experimentalExpand
Effect of Iron Phase Evolution on Copper Separation from Slag Via Coal-Based Reduction
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 theExpand

Converter copper slag can be viewed as an important secondary resource for valuable metals, considering its high commercial value. The current research investigates the recycling of copper by aExpand
Characterization of Copper Slag
Copper slag can be treated as a secondary resource since it usually contains a substantial amount of copper and other valuable metals. Characterization of the slags to determine the expected metalExpand
The Viscous and Conductivity Behavior of Melts Containing Iron Oxide in the FeOt-SiO2-CaO-Cu2O System for Copper Smelting Slags
The control of the slag properties has become very essential in improving (1) the separation between the slag and the matte and (2) the operation of electric smelting furnaces in the copperExpand
An Efficient Technology for Smelting Low Grade Bismuth-Lead Concentrate: Oxygen-Rich Side Blow Process
An efficient technology for low-grade bismuth-lead concentrate smelting is reported. In the process, two oxygen-rich side blow furnaces (OSBF) are used for oxidative smelting of the concentrate andExpand
Recovery of Copper and Magnetite from Copper Slag Using Concentrated Solar Power (CSP)
On the one hand, copper slag is nowadays a waste in copper pyrometallurgy despite the significant quantities of iron (>40 wt. %) and copper (1 to 2 wt. %). On the other hand, solar energy, whenExpand
Physicochemical Properties of the Molten Iron-Rich Slags Related to the Copper Recovery
The properties of a molten slag play an important role in the separation of the slag from the matte during copper smelting. In this study, the viscosity, electrical conductivity, density, and surfaceExpand
Innovative methodology for separating copper and iron from Fe-Cu alloy residues by selective oxidation smelting
Abstract The Fe-Cu alloy, that is generated at the bottom of an electric furnace (EF) in a zinc pyrometallurgical smelter, is considered as a kind of solid waste. To separate the copper and iron fromExpand
