摘要
利用X射线衍射和化学分析方法对滨海型钛铁砂矿进行了检测分析。结果表明:滨海型钛铁砂矿主要由18.1%的钛铁矿和77.4%的铁金红石组成,原钛铁矿中的Fe(Ⅱ)大部分氧化成Fe(Ⅲ)。利用还原-流态化浸出法,从滨海型钛铁砂矿制备了人造金红石,利用X射线衍射、光学显微镜、化学分析和粒度筛分对产物人造金红石进行了检测分析。结果表明:该人造金红石是金红石型TiO2,其中TiO2含量(质量分数)为96.12%,CaO+MgO含量为0.21%,多孔空心结构,+150μm粒级占96.5%,属于高端人造金红石产品,是氯化钛白和海绵钛生产的理想原料。
Analysis on beach ilmenite placer was conducted by X-ray diffraction （XRD） and chemical analysis. Results indicated that the beach ilmenite placer was comprised of 18. 1% ilmenite and 77.4% nigrine, and Fe（Ⅱ） in the ilmenite was mostly oxidized to Fe （Ⅲ）. The synthetic rutile was prepared from beach ilmenite placer by reduction- fluidization leaching method. Analysis on the synthetic rutile was conducted by XRD, optical microscope, chemical analysis and grain size screening method. The results showed that the synthetic rutile was a rutile type TiO2, in which the content（mass fraction） of TiO2 was 96.12% , the content of CaO and MgO was 0.21% and particle size of ＋ 150 μm accounted for 96.5% with perforated hollow structure. It was a high-end product of synthetic rutile and an ideal material for producing chloride titanium dioxide and sponge titanium.
