The Extraction of Copper - Chemistry LibreTexts
Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining (e.g., via froth flotation). Figure 1: Chalcopyrite extracted from Zacatecas, Mexico.
Solvometallurgical process for extraction of copper from ...
increase the copper extractions.37–40 Methanesulfonic acid, an organic acid was used as an alternative for mineral acid for extraction of copper from chalcopyrite.41,42 However, these systems were in general water-rich processes. In this paper, we describe a green solvometallurgical process for the extraction of copper from sulfidic ore minerals,
Microwave improving copper extraction from …
Microwave enhances copper extraction from chalcopyrite through modifying the surface structure. The surface morphologies of cubic chalcopyrite during leaching were showed in Fig. 4. In order to accurately reveal the leaching behavior, the microphotographs are obtained on in-situ observation of fresh and reactive chalcopyrite.

extract copper from chalcopyrite - …
Copper is recovered from chalcopyrite by means of a pollutionfree hydrometallurgical process which entails leaching and converting the chalcopyrite with On the other hand, the sample that was initially treated with the copper sulfate leach reaction yielded a 95% copper extraction, with only 1.3 …
Chloride leaching of chalcopyrite - ScienceDirect
In this work, two new process flowsheets, shown in Fig. 1, Fig. 2, were developed featuring chloride leaching of chalcopyrite combined with solvent extraction and conventional sulfate electrowinning to address the issue of recovering a pure product.They differ, however, with respect to iron deportment. The Hematite Process, in which no air is introduced to the leach, allows separate sulfur and ...

Copper Mining and Extraction Sulfide Ores
Stage 3: Roasting At this stage of the process, the stone reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite – CuFeS 2.From the formula, it is clear that iron and sulfur have to be removed in order to produce copper.
