摘要
湖北兴山瓦屋Ⅱ、Ⅲ矿段磷矿属沉积型磷矿床。磷矿物以胶磷矿为主，构成不同规模的条带分布。组成条带状、条纹状、致密块状矿石。磷在不同成分条带中的含量不同。通过对不同成分条带原矿石进行工艺性质的研究，并结合化学成分特点，对Ｐ２Ｏ５及有害杂质ＭｇＯ进行了化学平衡。为矿床的地质评价及合理开发利用提供了理论依据。
Abstract The ore blocks Ⅱ--Ⅲ of the Wawu phosphate deposit in Xinshan,Hubei,have a sedimentary origin and are prodominated by collophane which occurs as bands of varying scales to form different ores such as banded, streaked and massive.Compositions of the bands and streaks differ,so do the propositions of phosphate in them. Researches on the banded and streaked ores of varying compositions in terms of their processing properties, coupled with modeling chemical balance between the useful comPOnent P2O5 and the harmful component MgO,provide theoretical base for geological evaluation and future efficacious utilization of the blocks.
