国内外磷矿资源利用现状、趋势分析及对策建议

世界上约66%的磷矿石用于生产磷肥,磷矿的合理开采和利用直接关系国家粮食安全以及人类的生存发展,磷矿工业的可持续发展对化肥工业和农业生产均具有重要意义。本文在总体研究世界范围内磷矿资源储量现状及供需关系的基础上,重点介绍了中国磷矿资源特点、勘查开发及利用现状,并对中国磷矿资源未来开发利用趋势进行了分析。结果表明,未来中国富磷矿石供应短缺、磷矿资源开发利用势必加速整合与转型升级。最后依据中国磷矿资源消费预测成果,结合中国磷矿资源未来开发利用发展趋势,提出了合理开发磷矿资源、实现磷化工产业的可持续发展的建议。

Status and tendency analysis on utilization and suggestion of phosphorus ore resourcesat home and abroad

Phosphorus is essential for crop growth. Most of the phosphorus, which is applied to agricultural land, comes from phosphate rock. About 66% of the phosphate rock ore mined was used to produce phosphate fertilizer. A reasonable exploitation and utilization of phosphate rock is a key to the national food security and human survival. Sustainable development of the phosphate rock industry is important for the fertilizer industry and agricultural production. Based on the current relationship of reserves and production-demanding of phosphorus ore resources around the world, the characteristics, exploitation and utilization situation of phosphorus ore resources in China have been introduced, and their trend of exploitation and utilization has been analyzed. The result shows that there will be a short supply of rich phosphorus ores and a notable trend of combination of phosphorus resources, and that the transformation and updating of their exploitation and utilization would inevitably accelerate. According to the prediction and the trend of exploitation and utilization of phosphorus ore resources consumption in China, advices on their reasonable exploitation have been given to sustain the development of the phosphorus chemical industry.
