Characteristics and utilisation of copper slag—a review

01/11/2003· Copper slag has been carbothermally smelted in a submerged electric arc furnace, partially reducing FeO to a metallic phase comprising of copper and other metals by Acma et al. (1992). The metallic phase has been transformed to the granules by passing through an air jet. The granule after grinding was leached with H

Minimization of Copper Losses in Copper Smelting Slag

01/11/2012· From thermodynamic considerations, from industrial experience, and from the results obtained in this study, the minimum soluble copper content in the electric furnace slag is expected to be near 0.55 wt.% Cu. This level does not account for a portion of the copper present as mechanically entrained matte/metal droplets.

An Innovated Application of Reutilize Copper Smelter Slag

During the copper smelting process, copper-rich matte (sulphides) and copper slag (oxides) are formed as two separate liquid phases due to the addition of silica, forming strongly bonded silicate anions by combining with the oxides. The molten slag is discharged from the furnace at 1273–1573 K.

What is a Copper Slag? (with pictures) wiseGEEK

25/05/2020· Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.

Copper Slag an overview ScienceDirect Topics

The chemical composition of copper slag varies with the type of furnace. The typical composition of smelting slags is Fe (as FeO, Fe 3 O 4) 30–40%; SiO 2 35–40%; Al 2 O 3 up to 10%; and CaO up to 10%. The density of copper slag varies between 3.16 and 3.87 g/cm 3 based on the amount of iron content. The average specific gravity of copper slag is about 3.5 g/cm 3, which means copper slag is

Copper extraction Wikipedia

Gill quotes a copper in slag value of 0.23% for a wet-charged reverberatory furnace vs 0.37% for a calcine-charged furnace. In the case of calcine-charged furnaces, a significant portion of the sulfur has been eliminated during the roasting stage, and the calcine consists of a mixture of copper and iron oxides and sulfides. The reverberatory furnace acts to allow these species to approach
