| 摘 要： | 凹凸棒石矿为稀有的非金属矿种，近年来，在甘肃中、西部第三纪地层中发现了大型凹凸棒石矿，矿石总储量可达2.5亿吨，矿石中碘含量较高，西部凹凸棒石含碘约为0.0418%，中部平均含量约为0.0425%，与智力碘硝石的含碘量（0.04%）相当。伴生碘总资源量可达11.7万吨，其中水溶性碘占80%以上，这是世界上首次发现的含碘凹凸棒石矿。将含碘凹凸棒石作为鸡饲料添加剂可以提高产蛋量，所产蛋含碘22～57mg/kg。 |

| Abstract: | 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. Total reserves of iodine are up to 117,000 tons, with water_soluble iodine higher than 80%. The output of eggs is obviously raised by using iodic attapulgite as chicken feed additives and the iodine content of eggs can reach 22~57 mg/kg. |
