Chalcopyrite was the mineral upon which Bronze Age civilizations were built. Within the last century, it also became the mineral foundation for our modern electrical age. Our primary source of copper, chalcopyrite's name comes from the Greek words 'chalkos' and 'pyrites', which respectively mean 'copper' and 'striking fire'.

Three of the processes introduced above have made great strides in solving these problems for the extraction of copper from chalcopyrite: The GEOCOAT™ Process - A heap leaching process that is capable of bioleaching copper concentrates. It does this by coating the concentrate slurry onto a support rock, or substrate material, and stacking this coated material in a bioxidation heap.
There are many types of copper ore found throughout the world. Picture 4 shows the distribution of these deposits. About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting …
