Copper Concentrate - an overview ScienceDirect Topics
Copper smelting plants separate elemental copper from copper concentrates through multiple sulphide oxidizing stages. The considered smelting process includes a continuously functioning flash smelting furnace (FSF) and several Pierce-Smith converters operated in batches. Automating scheduling provides advisory information to operators.

How is Copper Made? What Is Copper Made of?
The Copper Smelting Process After the waste is separated, the iron and sulfur must be removed from the copper concentrate. Called smelting, the process usually involves one or two furnaces. The process starts by feeding the copper concentrate into a furnace along with a silica material called flux.

In some cases, the concentrate is submitted to an additional processing step to extract a by-product (e.g. molybdenum sulfide). Finally, the copper concentrate is dried ready for transportation to the next step (smelting). The copper concentrate production process does not involve any chemical modification of the original ore body. 2.
