滇中牟定县戌街晶质石墨矿的矿石类型与品质特征

Ore type and quality characteristics of Xujie crystalline graphite deposit in Muding County,Central Yunnan

云南省牟定县戌街晶质石墨矿调查评价中,采集了10件晶质石墨矿工艺粒度测量样、19件岩矿鉴定样、73件固定碳化学分析样。根据测量、鉴定、化学分析资料,从三个角度对矿石进行了类型划分和特征研究。据晶质石墨矿工艺粒度角度将矿石划分为4种类型,据赋矿岩石种类将矿石划分为7种类型,据固定碳含量,岩石、矿石划分为3种类型。本文对测量、鉴定、化学分析资料的统计分析方法,对不同地区晶质石墨矿的研究具有一定程度的参考意义。

In the investigation and evaluation of Xujie crystalline graphite deposit in Mouding County,Yunnan Province,10 samples of crystalline graphite ore process particle size measurement,19 samples of rock ore identification and 73 samples of fixed carbon chemical analysis are collected.According to the data of measurement,identification and chemical analysis,the ore types and characteristics are studied from three aspects.According to the process particle size of crystalline graphite ore,the ore is divided into 4 types.According to the type of ore-bearing rock,the ore is divided into 7 types.According to the fixed carbon content,the rock and ore are divided into 3 types.In this paper,the statistical analysis methods of measurement,identification and chemical analysis data have the certain reference significance for the study of crystalline graphite deposit in different areas.
