摘要
对贵州威宁沉积型赤铁矿石进行了工艺矿物学研究,重点研究了该矿石的矿物组成、主要矿物嵌布特征和主要含铁矿物赤铁矿的单体解离情况。研究表明,该矿石属于低磷、低硫、微细粒嵌布的赤铁矿石;矿石中主要铁矿物以赤铁矿为主,其次为磁铁矿和褐铁矿,主要脉石矿物以石英为主,其次为绿泥石、云母、高岭石等粘土矿物;赤铁矿嵌布粒度极细,平均粒度0.015mm,且赤铁矿与脉石矿物嵌布关系复杂。本研究为该矿石的开发利用提供基础资料。
It makes process mineralogical study on sedimentary hematite in Weining,emphasis on the mineral component,dissemination characteristics of the main mineral and the monomial dissociation condition of the main ore bearing hematite.The result shows,the ore is the hematite of low phosphate,low sulphur and micro-fine dissemination,the main mineral in the ore is hematite,others are magnetite and limonite,the main gangue mineral is quartz,others are chlorite,mica,kaolinite and so on.The dissemination size is very small,the average size is 0.015mm and the dissemination relation between hematite and gangue mineral is very complex.This study will afford basis data for the development and utilization of this ore.
