Write the reaction involved. Draw a labelled diagram of the electrolytic cell used for the refining of copper. Explain the variour steps supported by chemical equations. Draw labelled diagram from the electrolytic refining of copper. Explain the various steps supported by chemical equations.

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. 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. Chalcopyrite also known as copper pyrites and similar sulphide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated by, for example, froth flotation before refining.

In the extraction of copper from its sulphide ore

Crushing and concentration: The ore is crushed and then concentrated by the froth-flotation process. Roasting: The concentrated ore is roasted in excess of air. During the process of roasting,. Copper pyrite is partly converted into sulphides of copper and iron. Smelting: The roasted ore is mixed with powdered coke and sand and is heated in a blast furnace to obtain matte and slag. The slag is removed as waste. Bessemerisation: The molten matte is transferred to Bessemer converter in order to obtain blister copper. Ferrous sulphide from matte is oxidised to ferrous oxide, which is removed as slag using silica. Byju's Answer.

The Process The concentrated ore is heated strongly with silicon dioxide silica and air or oxygen in a furnace or series of furnaces. Was this answer helpful? We'll start by looking at the second reaction because it is much easier to see what is happening. Exploring the redox processes in this reaction It is worthwhile spending some time sorting out what the reducing agent is in these reactions, because at first sight there does not appear to be one! View Text Solution. The copper II sulfate solution has to be continuously purified to make up for this. In this process Cu2S behaves as reducing agent. What steps will be required to obtain metal from the enriched ore? Explain with equations of the reactions involved. Menu Categories. Describe the series of steps involved in the extraction of wool. Draw a neat and well labelled diagram for electrolytic refining of copper. The copper II ions are removed again from the organic solvent by reaction with fresh sulfuric acid, producing a much more concentrated copper II sulfate solution than before.

Name the metal which is extracted from the ore called 'Rock salt' b Name two ores of zinc.

During electrolytic refining of copper some metals , present as impuri Copper I sulphide Cu 2 S 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. In the extraction of copper from its sulphide ore, the metal is finally obtained by tbe reduction of cuprous oxide with :. Give the reaction involved during the extraction of zinc from its ore by a roasting of zinc ore b calcination of zinc ore Give the steps involved in the extraction of metals of low and medium reactivity from their respective sulphide ores. Subject Chosen Chemistry. Identify the alloy containing a non metal as a constituent in it A metal which exists as a liquid at room temperature is obtained by heating its sulphide ore in the presence of air. The blister copper is first treated to remove any remaining sulfur trapped as bubbles of sulfur dioxide in the copper - hence "blister copper" and then cast into anodes for refining using electrolysis. Which mercury compound is present in this ore? For every zinc ion going into solution there will obviously be one fewer copper ion formed. You have to use some chemical knowledge as well.
