Extraction of Copper: Detailed Process
The principal copper ores are: (i) Copper glance; Cu 2 S (ii) Copper pyrites; CuFeS 2 (iii) Malachite; Cu(OH) 2 CuCO 3 (iv) Cuprite or (Rubby copper); Cu 2 O (v) Azurite; 2CuCO 3.Cu(OH) 2. Today, chalcopyrite (CuFeS 2) is the most frequent source of copper ore, accounting for around fifty percent of copper production.

Solvent extraction of metals: Role of ionic liquids and microfluidics
The extraction of metal ions using the solvent extraction method has been started in the 1950s with the extraction of uranium from its ores and later for tantalum and niobium [25], [26]. Organic solvents such as xylene [27], kerosene [28], n-heptane [29], methyl-isobutyl ketone (MIBK) [30] and chloroform [31] are commonly used for the ...

Solvometallurgical process for extraction of copper from sulphidic ore
As the future copper requirements are much larger than what can be obtained through (even perfect) copper recycling from urban mines, there will be a need for the primary mining of copper. Unfortunately, extraction of copper from sulphidic ores, either by pyrometallurgy or hydrometallurgy, is typically associated with a relatively large …

Extractive Metallurgy of Copper
About 80% of the world's primary copper is produced by concentration, smelting, and refining of sulfide ores. The other 20% is produced by heap leaching, solvent extraction, and electrowinning of oxidized and chalcocite ores. Secondary copper production from recycled end-of-use objects is 15%–20% of primary copper production.

19.1: Properties of Transition Metals and Their Compounds
The most important ores of copper contain copper sulfides (such as covellite, CuS), although copper oxides (such as tenorite, CuO) and copper hydroxycarbonates [such as malachite, Cu 2 (OH) 2 CO 3] are sometimes found. In the production of copper metal, the concentrated sulfide ore is roasted to remove part of …

Abstract. 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 …

3.3.4 Copper extraction :: GCSE notes
Traditional methods. Copper is usually sourced from copper-rich ores in two main methods; Copper can be smelted in a furnace by heating it with air to produce crude copper metal; for example, chalcocite is an ore of copper (I) sulfide, which reacts with oxygen to extract the copper: Cu 2 S (s) + O 2 (g) → 2Cu (s) + SO 2 (g) Copper ore …
