Current Status of Copper-Ore Processing: A Review

In recent times, a low copper content in ores has been observed (ores containing 0.2–0.3% copper are used for processing in Canada and the United States, and ores containing at least 0.4% copper are used in Russia []) owing to the exhaustion of rich copper resources.The flowsheet of processing copper ores is developed for each hydrometallurgical treatment of copper and zinc-containing WASTES AT THE TZAR ASEN PLANT, BULGARIA Todor Angelov 1,Georgy Savov 1,Irena Grigorova 2,Ivan Nishkov 21, Georgy Savov1, Irena Grigorova2, Ivan Nishkov2 ResearchGate

The Extraction of Copper Chemistry LibreTexts

This is used to make sulfuric acid via the Contact Process. An overall equation for this series of steps is: 2CuFeS2 + 2SiO2 + 4O2 → Cu2S + 2FeSiO3 + 3SO2 (1) (1) 2 C u F e S 2 + 2 S i O 2 + 4 O 2 → C u 2 S + 2 F e S i O 3 + 3 S O 2. The copper (I) sulfide produced is converted to copper with a final blast of air.Furthermore, the biotechnological potential of these isolates in consortia form was evaluated to recover copper and zinc from their ore. Under optimized conditions, 77.68 ± 3.55% of copper and 70.58 ± 3.77% of zinc were dissolved.
