Table 24. — Estimated world reserves and resources of ehromite ore by type and country 



[Thousands of lonB tons of shipping ores and concentrates. A, high-chromium ore. CraOs more than 46 percent, Cr:Fe more than 2:1. B, high-iron 

 ore, CrsOs 40-46 percent, Cr:Fe 1 5:1 to 2:1. B-, high-iron ore, Cr-Oa less than 40 percent. Cr:Fe 1.6:1 or less. C, high-aluminum ore, AhOs more 

 than 20 percent, AbOa -j- CriOs more than 60 percent; (C), amount not estimated. (S), layered or stratiform. (P), podshaped. (PI), placer, sub- 

 ordinate. References cited are for subeconomic resources in the United States and for reserves in the rest of the world; all other estimates are 

 extrapolated by the author from reserve figures and the geology of the deposits and are intended only to indicate possible order of magnitude of 

 potential ehromite resources]
