extraction of copper for its ore

The Extraction of Copper Chemistry LibreTexts

Aug 21, 2020· Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (\(CuFeS_2\)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

copper extraction and purification chemguide

Extracting copper from other ores. Copper can be extracted from non-sulphide 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 sulphuric acid to produce a very dilute copper(II) sulphate solution.

Copper extraction by wet chemical method The resulting product was then applied to reduce copper in a solution leached from its ore. It was found that the reduced zero valent copper was 60–85% pure. This confirms that the chlorine treated chicken dung leached solution has potential for the extraction of copper from its ores at low cost.

Extraction Of Copper Mining, Concentration, Smelting

Jan 11, 2018· Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of Ore:

Copper Mining and Processing: Processing of Copper Ores

A. Processing of Oxide Ore. Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning.

Copper Ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

Extraction of Copper from Copper pyrite Grade 12 Science

The principal ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are: Crushing and Concentration: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation process.

Innovations: Introduction to Copper: Mining & Extraction

The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.

Oct 15, 2019· Zinc: The important ores of Zinc are Zinc blende, Z n S Calamine, Z n C O 3 Zincite, Z n O The extraction of zinc blende involves the following steps (i) Concentration: The ore is crushed and then concentrated by froth-floatation process. (ii) Roasting: The concentrated ore is then roasted in the presence of excess of air at about 1200K.

The Ancient History of Copper

Jan 25, 2020· The ability to extract copper from ore bodies was well-developed by 3000 BCE and critical to the growing use of copper and copper alloys. Lake Van, in present-day Armenia, was the most likely source of copper ore for Mesopotamian metalsmiths, who used the metal to produce pots, trays, saucers, and drinking vessels.

How is copper extracted from its sulphide ore? Explain the

Answer:In the extraction of copper from its Sulphide Ore, when ore is subjected to roasting some of it is oxidised to Cu2O which reacts with the remaining Cu2S to give copper metal. In this process, Cu2S behaves as reducing agent. 2Cu2S+3O2+heat→2Cu2O(s)+2SO2(g) 2Cu2O+Cu2S+heat→ 6Cu(s)+SO2(g) In electrolytic refining of copper, the

(iii) Cu2S (copper sulphide) Explaination Copper is usually extracted from its sulphide & oxide ores. Cu2O (copper oxide) is reduced to Cu (copper) by its reaction with Cu2S (copper sulphide). 2Cu2O + Cu2S --> 6Cu + SO2. SO2 gas is formed during this reaction & have to be safely removed from the reactor. Hope this helps you.
