Kennecott’s Bingham Canyon has produced more copper ore, 18.1 Mt, than any mine in the world.

Annual output is some 300,000 t of copper, along with 500,000 oz of gold, 4 Moz of silver, about 30 Mlb of molybdenum, and about 1 Mt of sulphuric acid

Last year, for the second in a row, Kennecott Utah Copper (KUC) producer of about 13% of Americas copper needs, was once again the Rio Tinto mine with the highest net earnings.
