4.1.6.3.1: Iron Production. Page ID. The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides.
For example, copper ore may contain sulfur, which can form sulfur dioxide during smelting . This can lead to environmental problems such as acid rain. Advertisement. 5. Extraction metallurgy process.

In this lab, you will extract copper from copper carbonate in two different ways, and then determine which industrial method is most effective. Method #1: Smelting. Smelting involves the use of a high-heat blast furnace and a reducing agent (like coke, which is a form of carbon) to extract the metal. In this case it is a two-stage reaction.
Extraction of copper from its natural form can be a tricky process. One of the equations that is used to describe copper extraction is Cu2S+2Cu2O→6Cu+So2. This equation illustrates how copper can be extracted from its ore by combining it with oxygen and sulfur. The reaction yields six atoms of pure copper and sulfur dioxide as a byproduct.
The correct option is A copper(I) sulphide 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
The process by which Zinc is extracted from its ore for the preparation of Zinc metal is known as Zinc mining. The most common ore of Zinc is Zinc blende which is a mineral of Zinc Sulphide. Other ores of Zinc are Calamine, Zincite, etc. Earlier, the extraction of Zinc was a very difficult process due to its low melting point.
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 …
A metal ore is a rock that contains enough of the metal to make it worthwhile extracting. They have to be extracted from their ores through processes such as electrolysis, using a blast furnace or by reacting with more reactive material. In many cases the ore is an oxide of the metal, therefore the extraction of these metals is a reduction ...
Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in …
Abstract Copper production by heap leaching, coupled with solvent extraction and electrowinning (SX-EW), is a well-established technology, with an annual output of about 3.7 million tonnes (Mt) of ...
After some time the air is turned off and self reduction of the oxide and sulphide occurs, giving impure blister copper which is 98% - 99% pure. Cu 2 S + 2Cu 2 O → 6Cu + SO 2. Impure copper is further refined electrolytically to obtain 99.95 - 99.99% pure copper by using a solution of Cu (II) sulphate as an electrolyte. Lead. Ore of Lead ...
Electrolytic refining of copper. Electrolyte: Solution of acidified Copper sulphate. Anode: Impure copper; Cu (s) → Cu 2 + (aq) + 2 e-Cathode: Strip of pure copper: Cu 2 + (aq) + 2 e-→ Cu (s) On passing electric current, …
Then electrolytic refining of copper is carried out to remove the rest of the impurities present in the ore. The impure copper is made anode and strip of pure copper are made cathode. On passing the current as shown in the diagram, the pure copper from the anode dissolves into an electrolyte. An equivalent amount of copper is deposited on the ...
4As + 3O 2 → 2As 2 O 3. The copper pyrite is partly converted into sulphides of copper and iron. 2CuFeS 2 + O 2 → Cu 2 S + 2FeS + SO 2. 2FeS + 3O 2 → 2FeO + 2SO 2. The Process in summary: The concentrated ore is heated stoutly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces.
