US5223024A - Hydrometallurgical copper extraction process ...

A process for the extraction of copper from a copper ore or concentrate comprises first subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure in the presence of oxygen and water to obtain a resulting acidic leach liquor which contains dissolved copper.

Extraction of Copper from Oxidised Copper Ore | Blablawriting.com

The method that would be used to extract copper from these ores is called roasting. Roasting involves the ore being roasted in a furnace with oxygen and during the process; the metal is converted into a copper oxide and then later the oxide is removed. b)Write a balanced chemical equation for the process used to extract copper from these ores.

Copper Mining & Extraction Process Flow Chart

There are two main process streams; one for sulfide ores and the other for ore that is being weathered to oxidize sulfides the so-called oxide ores. All ore in the pit is drilled and blasted and loaded into trucks and hauled for treatment if the ore is un-oxidized sulfidic ore then it needs to be crushed and milled to a fine slurry then it gets past through flotation cells in a concentrator to separate and concentrate the sulfides.

Extraction of Copper and Zinc | Chemistry Class 12 General ...

Occurrence and Extraction of Copper Occurrence of Copper. It occurs as native copper as well as in combined state.The main ores of copper 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. Extraction of Copper. It is mainly extracted from ...

In the extraction of copper from its sulphide ore the metal ...

In the extraction of copper from its sulphide ore the metal is finally obtained by the reduction of cuprous oxide with copper(I) sulphide. 2 C u 2 S + 3 O 2 → 2 C u 2 O + 2 S O 2 2 C u 2 O + C u 2 S → 6 C u + S O 2

copper processing | Definition History & Facts | Britannica

Copper processing the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. molten copper Molten copper being made into plates.

Extraction Of Copper | Mining Concentration Smelting ...

The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces calcium carbonate is added as a flux to create the slag. Iron in Chalcopyrite is removed as iron silicate slag. Most of the sulphur in Chalcopyrite turns into Sulphur dioxide (SO 2 ).

Common Extraction Processes for Copper Ore | Mining Pedia

All in all the processes used in the extraction of copper are often determined by the copper ore mineral processing conditions investment budget and other factors. It is suggested that the miner should learn about the copper ore properties and then select the single or combined copper extraction processes by the mineral processing test.

In the extraction of copper from its sulphide ore the metal ...

In the extraction of copper from its sulphide ore when ore is subjected to roasting some of it is oxidised to Cu 2 O which reacts with the remaining Cu 2 S (sulphide ore) to give copper metal. Cu 2 S +2Cu 2 O → 6Cu +SO 2 ↑ In this process Cu 2 S behaves as reducing agent.

copper extraction and purification - chemguide

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. Concentration of the copper (II) sulphate solution by solvent extraction.

Copper processing - Ores | Britannica

The first step mineral processing is to liberate the copper minerals and remove waste constituents—such as alumina limestone pyrite and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper. The second step involving either smelting or leaching removes a large proportion of impurity elements—in particular iron and in the case of sulfide ores sulfur.

The Extraction of Copper - Chemistry LibreTexts

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. Concentration of the copper (II) sulfate solution by solvent extraction.

Copper extraction by wet chemical method - ScienceDirect

Currently the extraction of copper is performed using a pyrometallurgical process that involves the use of electricity as well as coal both of which are expensive. The use of fossil fuels in extraction produces carbon dioxide which contributes to global warming. The other method used is solvent extraction followed by electro-winning (SX-EW).
