中低品位磷矿在热法制磷中的应用研究

Research on application of mid and low grade phosphate rocks in preparation of phosphorus by hydrothermal method

介绍了湖北神农架林区大白莲低品位磷矿的特点,通过调整工艺配矿和采用压球技术,使中低品位磷矿和黄磷尾气得到了利用,实现了绿色环保、清洁生产。

The characteristics of the mid and low grade phosphate rocks in Dabailian Mine, Shennongjialin District, Hubei are presented. The issue of utilization of the mid and low grade phosphate rocks and yellow phosphorus tail gas is addressed by adjusting the charge ratio and introducing the molding pressure ball technology, making the green, environment friendly and clean production of yellow phosphorus with the mid and low grade phosphate rocks.
