Question

Which one of the following is a leading producer of copper in the world ?
(A) Bolivia
(B) Ghana
(C) Chili
(D) Zimbabwe

Answer 1

Hint - Copper extraction refers to those methods that are used to obtain copper from its ores. There is a series of physical and electrical chemical processes in copper conversion. On the basis of ore source, local environmental regulations and other factors, methods are developed and different. As of 2017, Chile, the world's leading copper producer, produced an estimated 5.8 million metric tons of copper in 2017.

Complete answer - Global copper reserves as of 2017 by major countries. It was estimated that China has copper reserves of about 27 million metric tons. The figure placed China sixth in the global ranking based on copper reserves. As of 2017, with reserves of 11 million metric tons, Canada had the world's tenth largest copper reserves, and the world's ninth largest copper producer, with production of 620 thousand metric tons in the same year. 68% of Australia's economic resources are represented in South Australia, with 89 tonnes of copper. Most of it is hosted within the IOCG-style deposits within the Golar Cretan and the G2 Structural Corridor.
Global consumption of refined copper from 2010 to 2015. In 2010, copper consumption was 19.1 million metric tons worldwide. As of 2015, the total consumption of copper worldwide was 21.8 million metric tons. Most of the world's copper is also used in electrical applications, but also in architecture, automotive, electrical, tubes, pipes and fittings, fuel gas, industrial, marine, mechanized products, and telecommunications.

So option C is the correct answer.

Note - Copper is a chemical element with the symbol Cu and the atomic number 29. It is a soft, malleable and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a component of various metal alloys, such as sterling silver used in jewelry, cupronickel to make marine hardware and coins Is used for, and for constant temperature measurements used in stannel gauges and thermocouples.
