Copper Smelting Chemistry TutorialAny copper(I) oxide present will be converted into copper(I) sulfide during the smelting process because copper has a higher affinity for sulfur than it does for oxygen. for example: Cu 2 O + FeS → Cu 2 S + FeO. Impurities form a slag which floats on the surface and is easily removed. One of the reactions to remove iron impurities is shown below:

What Is Copper Smelting? (with pictures)Kirsten C. Tynan Copper wire. Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.
Copper: An Ancient Metal | Dartmouth Toxic MetalsBeginning in the late 1600s, copper smelting became a major industry in Great Britain. Copper ore from Cornwall and other areas and coal deposits throughout the country fueled the smelting of copper. An abundance of coal in Swansea, Wales made this coastal town a prime loion for Britain's copper smelting activities beginning in early 1700s.
AusIron processThe AusIron process takes place in a purposebuilt smelting reactor designed to withstand high operating temperatures and turbulence through a combination of copper cooling elements at the bath level and boiler tubes (membrane walls) loed at the upper part of the furnace. Ferrous feeds, fluxes, and reductant coal are fed gravimetrically from ...
6,000 years of copper smelting : Center for the Study of ...The architecture of the building is driven from the nature of the smelting process. In this process, copper is chemically separated from impurities in a smelting furnace. Heavy metallic copper sinks to the bottom of the furnace. Slag forms above the copper and gas evaporates. The layers of the building mimic this process and are made from ...
[PDF] Recovery of copper from the copper slag and copper ...Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron extractions were ...
