Chapter 6 Copper Production Technology
As early as 6000 B. C., native copper–the pure metal—was foundas reddish stones in the Med- iterranean area and hammered into utensils, weapons, and tools. Around 5000 B. C., artisans discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About

Copper Smelting Slideshow
Copper concentrate (CuFeS 2) is fed into the furnace along with a flux of silica sand, SiO 2, and oxygen, O 2. The flux is used to control the chemistry of the slag. In particular, it causes the iron (Fe) in the copper concentrate to accumulate in the slag phase, while the copper (Cu), accumulates in the matte phase. Copper Concentrate
Copper Smelting
The principal copper ore mineral is chalcopyrite (CuFeS 2), which is commonly smelted to yield a matte containing ∼50% copper.In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the Cu–Fe–S–O system at 1 atm SO 2 as a function of temperature (Rosenqvist 1978).Unlike the system for lead, the copper and …
Extraction of Copper: Detailed Process
This stage of smelting produces matte or copper matte, a copper-enriched combination of copper, iron, and sulfur. The objective of the matte smelting step is to remove as much iron, sulfur, and gangue minerals (such as silica, magnesia, alumina, and limestone) as possible while reducing copper loss.
Copper Mining & Processing: Everything You Need to Know
During the Industrial Revolution, coal- and steam-powered machinery paved the way for a considerable increase in copper production, with mines smelting between 200 and 300 tons of copper ore per week. At the beginning of the 20th century, the annual worldwide copper demand was half a million tons. By World War II, this demand had …
