Copper Smelting - an overview ScienceDirect Topics

W.G. Davenport, in Encyclopedia of Materials: Science and Technology, 2001 4 The Future. The major trend in copper smelting and converting is towards improved capture of the SO 2 that is evolved from oxidizing CuFeS 2 and other copper sulfide minerals. Improved SO 2 capture benefits the environment and the resulting H 2 SO 4 product can be used for leaching “oxide” and supergene sulfide ...

How Hydrometallurgy and the SX/EW Process Made Copper

Another advantage of the process is its low capital investment requirement relative to the smelting process and its ability to be operated economically in a small scale. In China, for example, where copper deposits are not plentiful and tend to be small, there are 40 to 50 "mom pop" leaching operations involving SX/EW.

Cupellation - Wikipedia

Process Large scale cupellation. Native silver is a rare element, although it exists as such. It is usually found in nature combined with other metals, or in minerals that contain silver compounds, generally in the form of sulfides such as galena (lead sulfide) or cerussite (lead carbonate). So the primary production of silver requires the smelting and then cupellation of argentiferous lead ores.

Ability to be operated economically on a small scale. It can be used on ore with as little as 0.1% copper – for this reason leaching extraction is growing in importance. It is estimated that SX-EW (virtually non-existent before 1960) will represent 21% of total copper refined production in 2019.

Small scale smelting can be done in a crucible – in fact that is what a fire assay is. When smelting assays are done on high sulfide ores, a couple of iron nails are added to the mix. The metal in the nails reacts with the metals in the sulfides reducing the metals to their metallic state.
