摘　　要：窑法磷酸工艺是近年中国自行开发的新工艺,是一种直接利用中低品位磷矿生产高纯度、高浓度磷酸的新的生产方法。简述了窑法磷酸工艺的起源和基本原理,指出窑法磷酸工艺的技术关键。介绍了国内外窑法磷酸工艺试验研究概况、技术开发历程。针对窑法磷酸工艺存在的问题,提出了窑法磷酸的研究方向和发展建议。Kiln-process phosphoric acid technology is a new technology self-developed in China in recent years. It is a new production method to produce high purity and high concentration phosphoric acid by directly using medium and low grade phosphorite. Origin and basic principle of kiln-process phosphoric acid production technology were briefly reviewed and key points in the technology were pointed out. General research survey and development history of kiln-process phosphoric acid production technology at home and abroad were introduced. At last, in allusion to the existing problems, research direction and development suggestions for kiln-process phosphoric acid were proposed.
