In the extraction of copper from its sulphide ore

The method used to extract copper from its ores depends on the nature of the ore. Chalcopyrite also known as copper pyrites and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining e. The concentrated ore is heated strongly with silicon dioxide silica and air or oxygen in a furnace or series of furnaces.

In the extraction of copper from its sulphide ore, the metal is finally obtained by the reduction of cuprous oxide with. 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 finally obtained by the reduction of cuprous oxide with. Reduction of Copper oxide done with Copper I sulphide. Which of the following elements is present as the impurity to the maximum extent in the big iron? Book Chosen Chemistry I.

Given below are the steps for the extraction of copper from its Sulphide ore: a Concentration of the ore : Removal of unwanted metals and gangue to purify the ore is done by Froth floatation method as it is a sulphide ore. Reduction of copper I oxide with copper I sulphide:. Menu Categories. Explain the steps for the extraction of copper from its sulphide ore. Write the balanced equations involved in the process. Tutorialspoint Simply Easy Learning.

Jump to navigation. The most common types of ore, copper oxide and copper sulfide , undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different chemistries of the ore. Copper oxides are more abundant near the surface, but are considered low-grade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit. On the other hand, while copper sulfide ores are less abundant, they contain higher amounts of copper.

In the extraction of copper from its sulphide ore

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. Note: You will find a brief description of froth flotation on the introduction to metal extraction page. The concentrated ore is heated strongly with silicon dioxide silica , calcium carbonate and air or oxygen in a furnace or series of furnaces. The copper II ions in the chalcopyrite are reduced to copper I sulphide which is reduced further to copper metal in the final stage. Most of the sulphur in the chalcopyrite turns into sulphur dioxide gas.

Recommended Content. The purification uses an electrolyte of copper II sulfate solution, impure copper anodes, and strips of high purity copper for the cathodes. Aluminium is extracted from Alumina Al 2 O3 by electrolysis of a mo Draw a neat and well labelled diagram for electrolytic refining of copper. Given below are the steps for the extraction of copper from its Sulphide ore: a Concentration of the ore : Removal of unwanted metals and gangue to purify the ore is done by Froth floatation method as it is a sulphide ore. How is copper metal extracted from its sulphide ore? Explain with equations. In many countries, as well as the more obvious copper-colored coins, "silver" coins are also copper alloys - this time with nickel; these are known as cupronickel alloys. 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. Text Solution. Give two examples of alloys. Iron sulphide FeS. In the extraction of copper from its sulphide ore, the metal finally obtained by the reduction of cuprous oxide with. Which ore of the following is a mineral of iron? The reducing agent is therefore the sulfide ion in the copper I sulfide.

Unreactive close unreactive A substance is unreactive or inert if it does not easily take part in chemical reactions. However, most metals are found combined with other elements to form compounds close compound A substance formed by the chemical union of two or more elements. Most metals are extracted from ore close ore A rock containing enough quantities of a mineral for extraction to be possible.

In the extraction of copper from its sulphide ore, the metal is finally obtained by the reduction of cuprous oxide with. Metals above copper in the electrochemical series like zinc will form ions at the anode and go into solution. Also, write the chemical equations for the reactions involved in the process. While extracting copper from its sulphide ore, the metal is finally obtained by the reduction of C u 2 O with :. Sign in. The iron in the chalcopyrite ends up converted into an iron II silicate slag which is removed. For every zinc ion going into solution there will obviously be one fewer copper ion formed. Figure 1: Chalcopyrite extracted from Zacatecas, Mexico. The copper II ions in the chalcopyrite are reduced to copper I sulfide which is reduced further to copper metal in the final stage.
