It is estimated that ~60% of global copper production comes from these deposits and as of January 2020, 14 of the top 20 largest operating copper mines in the world are exploiting porphyry copper deposits (Table 1). Copper production has kept pace with demand that steadily increased from ~12.9 Mt in 2000 to ~20 Mt in 2019 (USGS, …
