Jun 28 2017 most current copper extraction processes burn sulfide minerals in air which producessulfur 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 principal ore of copper is copper pyrite and copper is extracted from this ore the different steps in extraction of copper arecrushing and concentration the ore obtained from mines are broken down into small piece by jaw crusher and then pulverized the ore being sulphide ore is concentrated by froth floatation process
Extraction of copper copper pyrites is the main ore 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
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 which are often found in copper sulfides at
