mineral processing of copper from cacopyrite

Solvometallurgical process for extraction of copper from

Chalcopyrite is the most common copper-bearing mineral and accounts for approximately 70% of the copper deposits in the world. 1 At present, the main method for copper production from chalcopyrite is via pyrometallurgy, but it is only economically feasible for copper-rich feeds. Moreover, SO 2 emissions can cause environmental problems.

Electrolytic production of copper from chalcopyrite

01/08/2020· Hydrometallurgical techniques are in industrial operation to extract copper from oxide and secondary sulfide ores, but the treatment of chalcopyrite remains challenging. Chalcopyrite is the most refractory copper mineral. Harsh conditions (highly acidic solutions, high pressure and temperature, or thermal and chemical pretreatments) are required.

Solvometallurgical process for extraction of copper from

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).

Chalcopyrite Wikipedia

Chalcopyrite (/ ˌ k æ l k ə ˈ p aɪ r aɪ t,-k oʊ-/ KAL-ko-PY-ryt) is a copper iron sulfide mineral that crystallizes in the tetragonal system. It has the chemical formula CuFeS 2.It has a brassy to golden yellow color and a hardness of 3.5 to 4 on the Mohs scale.Its streak is diagnostic as green tinged black. On exposure to air, chalcopyrite tarnishes to a variety of oxides, hydroxides

All the copper minerals that contain iron element,such as chalcopyrite and bornite ,when they are in the alkalescent medium,the cyanide and lime cyanide their flotation. III. Because xanthate series collector is anion, it mainly react chemisorption with the Cu ion,so the minerals that contains more Cu ion will have stronger reaction with xanthate. Preferential flotation This method first

New approaches for extracting and recovering metals from

15/05/2017· The relatively high efficiency of copper bioleaching from the CLC tailings was unexpected given that much of this metal (68%) was deported in two minerals (chalcopyrite and enargite) that are usually regarded as recalcitrant, at least to conventional bio-processing (Watling, 2006).
