a method used in excracting copper

Oct 03 2013 · Extracting copper from its ores The method used to extract copper from its ores depends on the nature of the ore Sulfide ores such as chalcopyrite CuFeS2 are converted to copper by a different method from silicate carbonate or sulfate ores Chalcopyrite also known as copper pyrites and similar sulfide ores are the commonest ores of

Jan 11 2018 · Copper Smelting Smelting is a metallurgy technique to extract base metals from their ores with the help of heat and a chemical reducing agent Click here for extraction process 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

Extracting copper from its ores 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 Getting copper from chalcopyrite CuFeS 2

Jun 28 2017 · Most current copper extraction processes burn sulfide minerals in air which produces sulfur dioxide a harmful air pollutant that has to be captured and reprocessed but the new method produces elemental sulfur which can be safely reused for example in fertilizers The researchers also used electrolysis to produce rhenium and molybdenum

but they are still used because copper is so valuable Bioleaching and phytomining are increasingly used to extract copper from low grade ores see below The traditional method of extraction is to heat the copper sulfide Copper II sulfide gives copper and sulfur dioxide during thermal decomposition

Place these products in the extraction process in ascending order of copper content Use the flow chart as a guide Matte Ore Cathode copper Blister Anode copper Copper concentrate Fire refined copper Use a periodic table to find the atomic masses of the elements in cuprite and chalcocite Then work out the percentage of copper in each mineral

mining methods used to mine and extract copper2 Mining Methods CopperOpen pit mining is a technique used to extract copper ore near the earths surface Open pit mining is the most widely used technique of mining copper today It is accom

Bioleaching Certain bacteria can break down lowgrade ores to produce an acidic solution containing copper ions The solution is called a leachate and the process is called bioleaching

Evaluate the Use of Phytomining and Bioleaching in Metal We can extract the copper from this with electrolysis or by a displacement reaction with scrap iron Cu 2 aq FesCus Fe 2 aq Like phytomining bioleaching is a useful method for extracting metals from lowgrade ores

Open pit mining is a technique used to extract copper ore near the earths surface Open pit mining is the most widely used technique of mining copper today It is accomplished by creating and using benches or terraces to gradually reach deeper under the earths surface Underground mining is used when the copper ore is not near the earths
