Extracting of Copper from Other Ores. Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution.
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.
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.
This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. Before you get too bogged down in the extraction of copper, make sure that you need it for whatever syllabus you are using.
Extraction in chemistry is a separation process consisting in the separation of a substance from a matrix. It includes liquid-liquid extraction, and solid phase extraction. The distribution of a solute between two phases is an equilibrium condition described by partition theory.

The important ores of copper are copper pyrites (\(CuFeS_2\)), cuprite and copper glance. The copper ores are mostly found in the north of India. The extraction of copper also involves many steps. The ore used for extraction is copper pyrites, which is crushed,
Alternatively, students can remove the copper from the tube prior to weighing it and attempt to separate out the copper from the copper oxide. This gives a lower yield (neither is particularly accurate). Health Safety checked, 2016. Credits. This Practical Chemistry resource was developed by the Nuffield Foundation and the Royal Society of ...
5/10/2013 COPPER This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. Extracting copper from its ores The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores.
Copper Extraction by Fatty Hydroxamic Acids Derivatives J. Oleo Sci.61, (4) 189-195 (2012) 191 derivatives into acid solution. 3 RESULT AND DISCUSSION 3.1 Organic solvent selection and
Summary of Extraction of Copper from Copper Pyrites. Uses of Copper. Making copper wires and contacts in switches, plugs and sockets Reason: -Copper is a good conductor of electricity Note: -For this purpose, pure copper is necessary, since impurities increase
Copper is extracted from its ores using chemical processes that involve heat or electricity. Copper-rich ores are being used up and traditional mining and extraction have major environmental impacts. New ways of extracting copper. New ways are being found to extract copper from low-grade ores to reduce the environmental impacts of traditional ...
Stage 3: Roasting At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite – CuFeS 2.From the formula, it is clear that iron and sulfur have to be removed in order to produce copper.
Isolation of elements in Chemistry class 12 aims to teach the students about various processes of extraction of metals from ores. Very few metals such as the noble metals, i.e., Gold, Silver, and Platinum etc. are present in their original metallic forms in nature.
Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.
Rocks are made up of crystals of metals. An ore is a rock that contains enough of a metal compounds for it to be worth extracting the metal. The most common ores contain oxides. An example is the ore haematite, which contains iron (III) oxide. Some contain other metal compounds. Malachite contains copper (II) carbonate.
EXTRACTION OF COPPER FROM SULPHIDE ORE Large amount of copper are obtained from copper pyrite (CuFeS2) by smelting. Ores containing 4% or more copper are treated by smelting process. Very poor ores are treated by hydro-metallurgical process. EXTRACTION OF COPPER BY SMELTING PROCESS Following steps are involved in the extraction of copper.
Copper(II) oxide can be reduced to copper using hydrogen, showing the relative positions of copper and hydrogen in the reactivity series. This practical involves some specialist microscale equipment such as a comboplate® with lids and a microburner. If this equipment is available in your ...
Three of the processes introduced above have made great strides in solving these problems for the extraction of copper from chalcopyrite: The GEOCOAT™ Process - A heap leaching process that is capable of bioleaching copper concentrates. It does this by coating the concentrate slurry onto a support rock, or substrate material, and stacking this coated material in a bioxidation heap.
This is a common extraction process for the more reactive metals - for example, for aluminium and metals above it in the electrochemical series. You may also come across it in other cases such as one method of extracting copper and in the purification of copper.

This value gives copper extraction efficiency greater than 98% and copper stripping efficiency of 60%. Afterwards, understanding that copper extraction efficiency was not the most important parameter than the cost of copper production plant, one stage of stripping step was removed and the value of copper transfer was increased to 0.26 (g/l/1%V).

The labile copper(II) system formed by interacting with both the water and the IL cation component has been characterized by cyclic voltammetry as well as UV−vis, Raman, and 1H, 13C, and 15N NMR spectroscopies. The extraction process does not require the addition of a complexing agent or pH control of the aqueous phase.
