In the 20th century, new technologies like solvent extraction and electrowinning (SX/EW) made it possible to process low-grade copper ores, including copper oxide ores. Heap leaching also emerged as a significant technique for processing such ores, where the ore is crushed and placed in heaps, and a leaching solution is used to dissolve the copper.
The copper ore in Chilean copper porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in [...] Read more.
Copper Mining and Macroeconomic Indicators Copper mining has accounted for an average of 10% of Chile's gross domestic product (GDP) for the last two decades. In comparison, the mining industry as a whole represents 10.9% of GDP. Between 1996 and 2016, copper mining as a percentage of economic activity in Chile ranged between 3.6% (in 1998)

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.
Leaders in copper ore processing include Chile, Peru, the United States, Australia, China, Russia, Mexico, Kazakhstan, Zambia, and Congo. Chile accounted for almost a third of global copper …

The Chino open-pit copper mine in New Mexico Chalcopyrite specimen from Huarón mine, Peru Miners at the Tamarack mine in Copper Country, in 1905. The Old Copper Complex in North America has been radiometrically dated to 9500 BP—i.e., about 7480 BCE—making it one of the oldest known examples of copper extraction in the world. [2] The earliest evidence of the cold …
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
