| 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% Al~(3 ) 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 Al_2O_3 and rational choice of the technological processes of ore treating. |
