Precious metal extraction increased by a factor of 12.2 Aside from construction minerals and metals, growth in material extraction in OECD countries since 1980 has been modest, increasing by less than 1% annually and in some cases even decreasing (i.e. industrial minerals). Among OECD countries, the United States is the single largest extractor of material resources with 6.3 Gt extracted in 2010 - one third of all materials extracted in OECD countries. Australia, Canada, Mexico and Germany follow, each extracting between 1 and 1.8 Gt in 2010. The composition of material extraction and consumption are similar, with the exception that fossil energy carriers account for a slightly larger share of consumption than extraction in OECD countries, due to significant imports.
