中低品位胶磷矿的选矿研究

A Study on Beneficiation of Middle -and Low-grade Collophane Ores

用螺旋溜槽与浮选组成重一浮联合工艺选别中低品位胺磷矿，减少了环境污染，降低了生产成本，有效地利用了中低品位磷资源。对中低品位磷矿石的开发利用，有一定指导意义。

A combined spiral concentration/flotation flowsheet was employed to beneficiate middle and low -grade collophane ores. It is capable of implementing less environmental pollution,cost-saving opera tion,and effective utilization of middle-and low-grade phosphorus ore resources This study gives and approach to the development and utilizaton of this kind ores.
