Latin America remains the top region for copper discoveries. As detailed in our CES data set, this is unsurprising, as the region has attracted nearly 40% of annual copper exploration budgets over the past two decades. Chile and Peru alone account for 78.3% of the 648.7 Mt discovered in Latin America and 43.2% of the global total found …

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
