Economic mines are also operating in bulgaria, finland, portugal, spain and sweden. in 2010, eu mine production totalled 855,316 tonnes of copper (source: bgs), around 5.3 of world production. europe leads the world in copper recycling. recycling plays an important role in copper availability since todays primary copper is tomorrows.
For oxide ores and also for certain other ores and residues a wet process is used: solvent extractionelectrowinninghigh grade electrowon (commercial cathode) is sxew production that can be treated as refined cathode and sold as such. low grade electrowon is sxew production that must be rerefined. (sxew).
From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. the roasting process: changes some of the cufes 2 to copper oxide; removes some of the sulfur as sulfur dioxide; this is done by heating the concentrated ore from froth flotation. it is heated to between 500 c and 700 c in air.
