Review of copper pyrometallurgical practice: today and ...

Abstract. The pyrometallurgical processing of copper varies worldwide with respect to the charge materials, process, operating parameters, and the physical shape, size, and orientation of the vessel. Plant operations may be either batch, semi-continuous, or fully continuous to produce blister copper or other end product.

Pyrometallurgical Process - an overview ScienceDirect Topics

One process evaporates cadmium in an open furnace, and cadmium is recovered as cadmium oxide powder. In the other process, cadmium is distilled, in a controlled furnace atmosphere, giving cadmium metal powder and a high-content nickel alloy. Pyrometallurgy can also use other reactive gases (than air) to obtain metal separation.

Copper: smelting, producing and classification-Metalpedia

Copper: smelting and classification; The smelting of copper; Copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate. Then, after being smelted, refined copper and copper products are yielded. There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical.

The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu 2 S+O 2 → 2Cu+SO 2. The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves. This ...

23.2: Pyrometallurgy - Chemistry LibreTexts

Sep 08, 2020  In pyrometallurgy, an ore is heated with a reductant to obtain the metal. Theoretically, it should be possible to obtain virtually any metal from its ore by using coke as the reductant. For example, the reduction of calcium metal from C a O ( s): (23.2.7) C a O ( s) + C ( s) → Δ C a ( l) + C O ( g)

Dec 13, 2019  Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and ethylene glycol (EG) as organic solvent).
