目前,世界上对磷矿的需求量日益增加,而高质量的淋滤型矿体正在枯竭,因此,对碳酸盐含量高的磷矿物的处理,已引起世界选矿工作者的极大兴趣。许多研究工作已取得重大进展,有些选厂已将从磷酸盐矿石中有效地脱除碳酸盐的工艺应用于生产。本文论述了美国佛罗里达非淋滤型沉积矿石的碳酸盐脱除问题。
At present, the demand for phosphate rock in the world is increasing day by day, and the high-quality leaching ore body is depleting. Therefore, the treatment of phosphate rock with high carbonate content has drawn great interest from the world's miners . Significant progress has been made in many studies, with some beneficiaries applying processes that effectively remove carbonates from phosphate ores to production. This article addresses the carbonate removal of non-leaching sedimentary ore in Florida, USA.
