Copper ores are usually copper oxides, copper sulfides or copper carbonates. Most copper oxide ores do not contain a high enough percentage of copper to make direct smelting of the ore economically viable. Electrowinning can be used to extract the copper from these copper oxide ores. The process for extracting copper from copper oxide ores can ...

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.

Sulphide ores such as chalcopyrite are converted to copper by a different method from silie, carbonate or sulphate ores. So, extraction of Copper from it becomes very difficult it is a lengthy process because. (i) It contains many impurities in such a high amount that the percentage of Copper in it becomes only 23%.

The resultant enriched rocks are called copper ores. How is copper extracted from its ore Class 10? 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.

The Extraction of Copper Chemistry LibreTexts. Copper can be extracted from nonsulfide 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.

Flotation process are widely used for copper extraction. The ore pulp slurry is pumped to flotation cells for extracting. The flotation cells are divided into several parts: roughing, concentration and scavenging (the exact numbers of stages for each part should be decided by test work to reach the best recovery), and with the use of frothing ...

Copper is extracted from its principal ore copper pyrites (CuFeS 2). The ore is concentrated by froth flotation process. The concentrated ore is roasted in a reverberatory furnace when the following reactions occur. 1. The volatiles like sulphur and arsenic escape as gases S + O 2> SO 2 4AS + 3O 2>2AS 2 O 3 2.
