攀枝花直接还原钛渣的矿物学特征
|
摘要
以中国攀枝花直接还原钛渣为研究对象,采用化学分析、X线衍射分析和矿物解离度分析等对其矿物学性质进行研究。研究结果表明:直接还原钛渣中TiO2品位为46.80%,其中的矿物主要为黑钛石,质量分数为50.28%,其次为尖晶石、中长石、钛辉石、橄榄石和自然铁等。直接还原钛渣中各矿物相互之间均存在共生关系,且部分矿物颗粒共生关系复杂。Ti在各矿物中均有分布,其中绝大部分赋存在黑钛石中,分布率达到94.34%。直接还原钛渣在电炉熔分的过程中,镁等元素通过类质同象掺杂进入黑钛石晶体中,使黑钛石携带杂质元素。
The mineralogical characteristics of direct reduction titanium slag(DRTS) originated from Panzhihua, China were studied by numerous analysis, such as chemical analysis, X-ray diffraction analysis and mineral liberation analyser and so on. The results show that the grade of TiO2 in DRTS is 46.80%. Anosovite with content of 50.28% is the primary mineral, followed by spinel, andesine, titanaugite, olivine and native iron. The various minerals in DRTS exhibit a symbiotic relationship with each other, and some of the symbiotic relationships of these mineral particles are complex. Ti is distributed in various minerals, and most of Ti is present in anosovite with a distribution rate of 94.34%. In the process of DRTS melting in the electric furnace, magnesium and other elements are doped enters anosovite crystal through isomorphism, so that anosovite carries impurities.
