碳酸锰矿石中,磷在锰矿物及脉石中的分布特点是锰矿石降磷工艺中极为关注的问题。本文重点介绍了解决这一问题的一种较为有效的方法,即选择性浸溶一筛分分析法。并列举了对花垣、松桃高磷碳酸锰矿石的研究结果,论证了这一方法在磷的赋存状态和分布特点研究中的可行性。 Among the manganese carbonate ores, the distribution of phosphorus in manganese minerals and gangue is the most concerned issue in the manganese ores dephosphorization process. This article focuses on a more effective solution to this problem, namely selective leaching of a sieve analysis. The results of the study on high phosphorus and manganese carbonate ores in Huayuan and Songtao are also listed. The feasibility of this method in studying the state and distribution of phosphorus is demonstrated.
