Attapulgite deposits are rare and valuable in the world. Large iodic attapulgite deposits with total reserves of 2 500 million tons were found in central and western Gansu Province. High iodine exists in attapulgite ores. There is about 0.0418% iodine in western attapulgite ore and 0.0425% in central ore, which are almost the same as the iodine content of niter in Chile.
