摘要
以磷矿石的脉石矿物氧化钙含量（Ｃ＝ＣａＯ－１．３１·Ｐ２Ｏ５）为判别指标，将矿床风化程度划分为强风化、风化、半风化及原生四个带，上三带又分为六个亚带。在总结各带矿石化学组分变化规律的基础上，将矿床划分为五个特征组分含量带，从而提出不同品级、不同风化程度矿石的工业利用方向。
With the CaO content of the gangue mineral of P ore as a discrimination index (C=CaO -1. 31. P,O,), this ore doposit can be divided into 4 zones of intensively weathered, weathered, subweathered, and original ore. The upper 3 zones can be further divided into 6 subzones, Basing upon the summary of the variation law in the ore chemical composition of various zones,the ore deposit is divided into 5 content zones of the characteristic constituent, And the commercial utilization of different grade and weathered ores is put forward in this paper.
