Climax mine, the largest producer of molybdenum, is located in

  1. A.Canada
  2. B.USA
  3. C.Australia
  4. D.South Africa

Correct answer

B. USA

Explanation

The correct answer is B, USA. The Climax mine is in Colorado, in the Rocky Mountains near Leadville, and it was long the world's largest molybdenum mine.

Climax lies at a height of over 3,000 metres close to Fremont Pass. Large-scale mining of molybdenum began there around 1918, when the metal was in demand for hardening steel used in armour and guns during the First World War. For many decades it supplied most of the world's molybdenum, and its ore body gave its name to the 'Climax-type' deposits that geologists study. Molybdenum is mainly used in alloy and stainless steels, which it makes strong and resistant to heat and corrosion. Today China and the United States are the leading producers.

A is wrong because Canada's molybdenum comes mainly from mines in British Columbia, not from Climax. C is wrong because Australia is known for iron ore, bauxite and gold rather than this mine. D is wrong because South Africa is known for gold, platinum and chromium.

Exam tip: Climax mine, Colorado, USA: molybdenum, a metal used to harden alloy and stainless steels.
