Globally, economic copper resources are being depleted with the equivalent production of three world-class copper mines being consumed annually. Environmental analyst Lester Brown suggested in 2008 that copper might run out within 25 years based on what he considered a reasonable extrapolation of 2% growth per year. Fifty-six new copper discoveries have been made during the three decades 1975–2005. World discover
While the copper market is gaining momentum, it is a good time to look at the copper mining champions in terms of copper grade in ore reserves.
Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper
2019-11-25 The world's 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year, about 40% of the world's total copper mine capacity. Chile and Peru, alone, account for more than half of the copper mines on this list. The U.S.

In addition, recycling, innovation and mining exploration continue to contribute to the long-term availability of copper. Despite increased demand for copper produced from ore in recent years, increases in reserves have grown more, and there is more identified copper available to the world
One of most commonly mined minerals in the world is iron ore. The three biggest producers of the precious metal include Vale, BHP Billiton and Rio Tinto with the vast majority of mines in Brazil, Australia and Africa. Although the price for the metal has fallen in recent years, the demand is never ending. We examine the top 10 iron ore mine in the world based on proven and probable reserves.
Chile. The top producers of copper are found throughout the world. The number one producer is Chile, a South American country. Chile produces 5,750,000 tons of copper annually. The country attracted foreign private investments in the 90's when the government passed a mining law that compensation regulations for the case of mine nationalisation.
The known reserves of higher-grade ore in the world amount to nearly 1 billion tons of copper. At the present rate of mine production, which is about 13.9 million tons (12.5 million metric tons) a year, known reserves of copper could be depleted in about 65 years. However, successful exploration for new mineral deposits, technological advances ...

of copper-bearing minerals is classed as an ore reserve if there are sufficient quantities and con-centrations of minerals to be extracted at a profit. Commercial copper ore deposits today contain from 0.5 to 6 percent copper, or between 100 and 1000 times the crustal average. In contrast, iron and aluminum constitute around 5.8 percent
While most mines operate with copper concentrations of between 0.2 and 0.8 %, some of the richest ore bodies, located in central to southern Africa, can contain 5 – 6% copper. According to the US Geological Survey, since 1950, reports have regularly shown that there have always been, on average, 40 years of copper reserves and over 200 years of resources available.
Country distribution: In the world, copper resources are mainly concentrated in Chile, the United States, Zambia, Russia and Peru.

Copper is one of the few materials that do not degrade or lose their chemical or physical properties in the recycling process. Recycling has the potential to extend the use of resources and minimize waste. In 2014, the International Copper Study Group estimated that more than 30% of the world's copper consumption came from recycled copper.
