高磷铁矿石成分分析标准物质研制
|
摘要
高磷铁矿石的分析测试过程需要基体组分相似、含量适中、定值组分全的标准物质进行质量监控,目前我国没有高磷铁矿石标准物质,现有铁矿石标准物质因基体组分不尽相同,磷元素含量大部分低于0.25%,而高磷铁矿石中磷含量均高于0.25%,这些标准物质难以满足高磷铁矿石产品的分析测试质量监控要求。基于此,本文研制了3个高磷铁矿石成分分析标准物质,样品分别采集于鄂西地区湖北宜昌秭归县野狼坪矿区、湖北恩施长岭矿区(武钢矿区)、湖北宜昌长阳县火烧坪矿区(宝钢长阳矿区),磷和铁含量均呈一定梯度,基本覆盖高磷铁矿的含量范围。均匀性和稳定性对SiO_2、Al_2O_3、TiO_2、P、K_2O、Na_2O、Fe、MnO、CaO、MgO、FeO、LOI、S、Cu、Pb、Zn、Cr、Ni、Co、Cd、Sr、Ba、V、As、Hg共25个组分进行检验,均匀性检验采用方差分析F检验法和测试结果的相对标准偏差进行评价,稳定性检验采用直线拟合,t检验法进行评估。经检验,样品均匀性、稳定性良好;定值采用11家实验室协作,采用2种以上不同原理的方法进行测试,定值组分包括主量元素、微量元素共25项,其中24项提供认定值及不确定度,Hg提供参考值。磷的含量分别为0.285%、不确定度0.010%,0.735%、不确定度0.020%,1.73%、不确定度0.05%,总铁含量分别为35.18%、不确定度0.20%,41.46%、不确定度0.20%,51.44%、不确定度0.13%。本次研制的高磷铁矿石标准物质可用于高磷铁矿的勘查、评价和综合利用开发中对标准物质的需求。
BACKGROUND: The analysis and testing process of high-phosphorus iron ore requires quality control of standard materials with similar matrix components, moderate content and fixed value components. At present, there are no certified reference materials available for high-phosphorus iron ore chemical composition analysis in China. The available iron ore reference materials in China and abroad have different matrix compositions and phosphorus contents. Phosphorus content is mostly less than 0.25%, while phosphorus content in high-phosphorus iron ore is higher than 0.25%. It is difficult to meet the analytical quality control requirements of high-phosphorus iron ore products with these reference materials.OBJECTIVES: To develop three high-phosphorus iron ore reference materials with contents of iron and phosphorus forming a certain gradient and covering the content range of high phosphorus iron ore.CANDIDATES CHARACTERISTICS: The sample GPFe-1 is composed of 40% metallic minerals, 25% quartz, 15% colloidal phosphate, 20% oolitic chlorite, clay mineral, apatite, carbonate minerals, rock debris and a small amount of organic matter. The metal minerals are hematite, limonite and pyrite.The contents of iron and phosphorus are 31%-37% and 0.1%-0.5%, respectively. The sample GPFe-2 consists of 40% hematite, 5% limonite, 55% gangue mineral, and minor collophanite and pyrite. The iron and phosphorus contents in GPFe-2 are 38%-44% and 0.6%-1.0%, respectively. The sample GPFe-3 is composed of 70% metallic minerals(hematite, limonite, pyrite), 5% quartz, 1% collophane, 3% chlorite, 1% cuttings, and minor apatite and calcite. The contents of iron and phosphorus in this sample are 48%-55% and 1.4%-2.0%, respectively.METHODS: The samples of high-phosphorus iron ores were collected from the western Hubei Yelangping mining area in Zigui county of Yichang city, the Enshi Changling mining area(Wuhan iron and steel corporation mining area), and the Huoshaoping mining area in Changyang county of Yichang city(Bao Steel Group Changyang mining area). Uniformity and stability were tested for 25 components of SiO_2, Al_2O_3, TiO_2, P, K_2O, Na_2O, Fe, MnO, CaO, MgO, FeO, LOI, S, Cu, Pb, Zn, Cr, Ni, Co, Cd, Sr, Ba, V, As and Hg. Uniformity test was evaluated by variance analysis F test and relative standard deviation of test results. Stability test was evaluated by linear fitting and t-test.RESULTS: Three samples were homogeneous and stable. The RSD of major elements and trace elements of 3 samples was less than 5%. The F value of variance test was less than the critical value F_(0.05)(24,25)=1.96, indicating that all the components of 3 samples were homogeneous. The stability test showed that the components of 3 samples had no directional change and statistically significant differences, indicating that the elements in the 3 samples were stable. The verified value was tested by 11 laboratories and by two or more different principles. The verified value components included 25 major elements and trace elements. Three components of Na_2O, S and Hg of GPFe-1 had reference values, whereas other 22 components had certified values and uncertainties. The contents of iron and phosphorus in GPFe-1 were 35.18%±0.20% and 0.285%±0.010%, respectively. Two components of Cd and Hg in GPFe-2 had reference values, and other 23 components had certified values and uncertainties. The contents of iron and phosphorus in GPFe-2 were 41.46%±0.20% and 0.735%±0.020%, respectively. Two components of FeO and Hg in GPFe-3 had reference values, while other 23 components had certified values and uncertainties. The contents of iron and phosphorus in GPFe-3 were 51.44%±0.13% and 1.73%±0.05%, respectively.CONCLUSIONS: The developed high-phosphorus iron ore reference materials meet the requirements for exploration, evaluation, and comprehensive utilization of high-phosphorus iron ore.
