The reserve totals imply global R/P ratios of 61 for crude ore and 27 for its metallic content. Iron ores are found worldwide, but, as with most minerals, massive deposits (as well as high-quality reserves) are unevenly distributed, with Australia (26%), Brazil (18%), and Russia (16%) accounting for 60% of global iron reserves.
