含钒磷铁矿物分析

Mineral Analysis of Ferro-phosphorous Containing Vanadium

以含钒磷铁矿物为例,介绍了复杂矿物的矿物分析过程及其方法,为从事矿物冶金相关行业的工程师和相关研究人员提供可借鉴的经验。同时也系统性的提供了含钒磷铁矿物分析方面的数据和分析结果,以供含钒磷铁相关研发人员借鉴使用。采用X射线荧光分析、X射线衍射分析、综合热分析等手段对含钒磷铁的矿相组成、元素组成、物相组成和综合热变化进行详细分析,结果表明:含钒磷铁矿由钒磷铁矿和磷铁矿两种矿相组成;其元素组成比较复杂,金属元素总含量超过检出元素的70%;含钒磷铁矿物中主要为各种合金,有部分单质磷等非金属单质,也有少量矿化物;在加热过程中,含钒、磷、铁矿物中的钒、锰、铌、铬、铁等容易同时发生反应而混杂在一起,很难只通过控制温度实现钒、铬、铁三种元素的分离。

Taking Ferro-phosphorous containing vanadium as an example, the mineral analysis process and methods of complex minerals were described,and the useful experience was provided to engineers and research staffs of the related industries engaged in mineral metallurgical. At the same time, the data and analysis results of mineral analysis of Ferro-phos-phorous containing vanadium were also systematically provided, which can be learnt and used by related research and devel-opment personnel. By describing the mineral analysis process and methods of Ferro-phosphorous containing vanadium in detail,a detailed analysis of mineral phase composition, elemental composition,phase composition and integrated thermal changes of it were completed, by means of X-ray fluorescence analysis, X-ray diffraction analysis, comprehensive thermal analysis, etc. The results showed that there are two kinds of main mineral phase in Ferro-phosphorous containing vanadium： vanadium phosphorus iron ore and phosphorus iron ore. Its element is very complex, and the total content of the metal ele-ment exceeds seventy percent of the elements. There are a variety of alloys in Ferro-phosphorous containing vanadium, inclu-ding some elemental phosphorus and other nonmetallic substance, and also a small amount of mineralization. During the heat-ing process, the vanadium, manganese, niobium, chromium and iron in it are so easy to react simultaneously and then mixed together. So it is difficult to separate the three elements vanadium, chromium, and iron by just controlling the temperature.
