In this study, a hydrometallurgical process for copper extraction from chalcopyrite in [EMIm]HSO 4 aqueous solution with potassium dichromate was …

MIT Open Access Articles Electrolytic production of …

A vision is proposed in which an electrolytic technique, integrated with low cost and sustainable power, enables the production of unprecedented annual tonnages of copper …

Extraction of copper from chalcopyrite concentrates without …

A gaseous chlorination process for the hydrometallurgical treatment of a chalcopyrite concentrate was investigated. The overall process is visualized to consist …

Mineralogical Characterization of Chalcopyrite Bioleaching

Chalcopyrite (CuFeS 2) is the most important copper ore, comprising approximately 70% of copper reserves in the world [1,2]. In metallurgical applications, …

Chalcopyrite Dissolution: Challenges | SpringerLink

In leaching tests with chalcopyrite and bornite in different ratios, the copper extraction was greater than 90% after 30 days in all tests containing the two minerals in a mixture …

A conceptual process for copper extraction from …

A conceptual flowsheet is proposed and the main processing steps are evaluated for the alkaline processing of chalcopyrite where glycine is the complexing agent. Glycine is utilised in an oxidising, alkaline environment to leach chalcopyrite at atmospheric …

Metals | Free Full-Text | The Extraction of Copper from …

Chalcopyrite, as one of the most widely found copper minerals in nature, exhibits slow dissolution kinetics due to surface passivation phenomena [ 10, 11, 12 ]. …

Hydrometallurgical Processing of Chalcopyrite by Attrition …

We report the investigation of a chalcopyrite leaching process that implements millimeter-sized glass beads that are stirred in the leach reactor to combine particle grinding, …

(PDF) Extraction of Copper from Chalcopyrite Using

A conceptual flowsheet is proposed, where chalcopyrite concentrate can be extracted by a leaching–grinding process and copper can be recovered by a solvent …
