摘 要：本文论述了广西贵港三水型铝土矿针铁矿中铝的类质同象置换现象和规律,并测定了置换率.研究表明,矿石的针铁矿中含铝17mol%左右.这对阐明矿床的形成环境,准确计算矿物量和氧化铝溶出率以及合理选择矿石加工工艺流程有重要意义.
Abstract: This paper discusses the appearance and regular pattern of the isompophous substitution of aluminium in the goethite in the gibbsite-type bauxite deposits occuring in Guigang,Guangxi.The research reveals that the goethite contains about 17 mol% Al3+ in the ore.This study has important significance in expounding the forming condition of ore deposits,exact calculation of the mineral amounts and available dissolve ratios of Al2O3 and rational choice of the technological processes of ore treating.
