Copper extraction - Wikipedia
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

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.
Extraction Of Copper | Mining, Concentration, …
Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulfides.The percentage of copper in the actual ore is too low for direct extraction of copper to be viable.
Solvometallurgical process for extraction of copper from ...
for copper extraction from chalcopyrite, which can be applied to low grade copper ores due to the lower operating costs.2 Many works have been reported for hydrometallurgical leaching of chalcopyrite. The most often used lixiviants are acidic chloride media, acidic sulfate media and basic ammonia solutions, together with various oxidizing ...
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.
Improving of copper extraction from chalcopyrite …
5-5-2018 · The addition of NaCl in the ammonium persulfate-APS (as an oxidant) leaching was investigated. APS has some advantages compared with conventional oxidants and its standard redox potential (E°) is 2.0 V. Effect of six parameters such as NaCl concentration, APS concentration, temperature, time, liquid–solid ration (L/S), and stirring speed on the leaching behavior was studied. …

Copper extraction from chalcopyrite: Comparison …
Copper extraction from chalcopyrite concentrate in media containing 0.1 M Fe 3+ as different salts; solutions were acidified to pH 1.5 with the relevant inorganic acid (H 2 SO 4, HCl or HNO 3) and heated to 50 °C prior to chalcopyrite addition.
Chalcopyrite Leaching - Metallurgist & Mineral …
Leaching Chalcopyrite is the holy grail for hydrometallurgists (Leachers), difficult to leach as the sulfur forms a layer over the mineral and makes the leaching slow. Having said that, it is not 100% not leachable, not unusual for ore dumps (low grade) containing chalcopyrite to be placed under leach but report low recovery +/-30% TCu over several years and the rate is around 0.5-1% per month ...
