Copper can be recycled indefinitely without the base metal being compromised ...

Slag - Wikipedia

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of ...

12.3 Primary Copper Smelting

Slag produced by flash furnace operations contains significantly higher amounts of copper than reverberatory or electric furnaces. Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide.

Minimization of Copper Losses in Copper Smelting Slag ...

Sep 21, 2012· During the last few decades, the pyrometallurgical processes used for cleaning copper smelting slags have been steadily optimized. The electric furnace or rotary slag-cleaning furnace are now generally used to perform this task, giving a level of copper in discard slag typically in the range of 0.55 wt.% and 1.3 wt.%, with most plants reporting copper losses in the discard slag in the range of ...

What is a Copper Slag? (with pictures) - wiseGEEK

May 25, 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.

Kinetics of Copper Reduction from Molten Slags

invariably lead to significant copper loss in slag, which needs to be recovered by means of reduction and settling in a separate slag cleaning furnace. Reduction of iron oxides from slags using carbon as a reductant in the form of dissolved carbon in iron or graphite has been studied extensively by a large number of researchers. A number of

Copper - Sulphuric Acid

Concentrate and oxygen-enriched air (30-35% O2) enter the smelting furnace through vertical lances and are smelted to produce a matte of 65% to 69% Cu and low-copper slag. Fuel must be burned to satisfy the heat balance in the smelter chamber. The high-grade matte flows to the electric slag cleaning furnace.
