Copper processing - Roasting, Smelting, Converting | Britannica
Copper processing - Roasting, Smelting, Converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements.
A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4 steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace.
Copper Mining and Processing: Processing Copper Ores
This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis.
Copper Smelting Process - Bright Hub Engineering
There are several methods of copper smelting, the popular ones being reverberatory smelting and oxygen flash smelting. Both methods require the resultant molten copper to be further processed to achieve a grade of 99.9% pure copper.
What is copper smelting? The method of extracting pure elemental copper (Cu) from copper concentrate (CuFeS 2).

Copper Smelting - an overview | ScienceDirect Topics
Typical copper pyrometallurgical process and the main chemical reactions of the smelting stage. The smelting process can be divided into three stages, namely decomposition of high-valence sulphide, oxidation of sulphide, and matte smelting and slagging reaction (Fig. 1).
Extraction of Copper: Detailed Process - Science Info
2023年4月4日 · Copper Mining. Mining is the initial phase in the extraction process. Copper ore must be extracted using either open-pit or subterranean techniques. Open-pit mining is the most efficient technique for extracting huge quantities of material from …
From Ore to Finished Product - Copper
From its original home buried underground in a mine to its use in a finished product such as wire or pipe, copper passes through a number of stages. When it is recycled it can pass through some over and over again.
