摘　　要：印尼某海滨砂钒钛磁铁矿工艺矿物学研究表明,该矿中多数钛磁铁矿是磁铁矿—钛铁晶石—镁铝(铁)尖晶石组成的均一固溶体,钛磁铁矿含TFe≥59%,TiO211.5%～12%,Al2O34%,MgO3%,钛磁铁矿单体解离度较高,少部分和脉石形成富连生体。钛铁矿有粒状和片晶状两种,它们都是钛铁矿和赤铁矿的均一固溶体。在矿石性质的基础上,阐明了矿石可选性。随着共伴生高温石英长石的进一步发现,钛磁铁矿和钛铁矿的火山成因得到佐证。The research on process mineralogy of vanadium titanium magnetite of a beach placer in Indonesia showed that most of the titanium magnetite was homogenization solid solution composed of magnetite,Ti-Fe microlite and Mg-Al（Fe） Spinel.More than 59%of TFe,11.5%～12%of TiO2,4%of Al2O3 and 3%of MgO are contained in the titanium magnetite,the degree of monomer dissociation of which is relatively high and a few of which are intergrown with gangues.There are graininess and tabular crystal ilmenit,both of which are the homogenization solid solution of ilmenite and hematite.On the basis of ore properties,the beneficiability or the ore was clarified.As the further discovery of the associated high temperature quartz feldspar,the volcano cause of titanium magnetite and ilmenite was proved.
