    中国钒矿成矿地质特征与资源潜力评价

    The characteristics and potential of vanadium resources in China

    • 摘要:研究目的】钒金属因其独特的物理和化学性能而用途广泛,在经济社会发展中起着越来越重要的作用。我国是钒资源大国,无论是总资源量还是产量、消费量均排列全球第一,对我国钒矿资源进行成矿规律总结和潜力分析具有重要的理论和现实意义。【研究方法】文章在系统梳理和全面总结全国钒矿成矿规律的基础上,开展了钒矿资源潜力评价。【研究结果】与黑色岩系有关的沉积型钒矿是我国查明资源量占比最多的钒矿类型,主要集中分布于扬子地块南北缘、秦岭-大别造山带以及塔里木地块北缘,海侵、生物有机质、热水液体共同作用下沉积的黑色岩系地层是寻找该类型矿床最重要的找矿要素。其次为与基性-超基性杂岩有关的钒钛磁铁矿型钒矿,主要分布于攀西裂谷、华北地台北缘及天山一带,成矿主要与切壳的深大断裂有关,带状分布的构造-岩浆岩带是寻找该类型矿床最重要的要素。潜在资源预测共圈定了213个预测区,包括A类预测区32个,B类预测区85个,C类预测区96个。【结论】综合考虑我国钒矿资源在全球供需链中的位置,以及我国钒矿品位较低、共伴生矿多、矿物组成复杂的特点,结合资源综合利用水平较低、资源浪费较大的现状,文章建议,为巩固和培养我国钒资源优势,对岩浆型钒钛磁铁矿应加大找矿投入,保证已有钒产业基地产能需求;对沉积型钒矿,应加强选冶技术研发,提高综合回收率;同时应加强高档钒产品的开发,提高对钒矿资源的高效、高端开发利用。

       

      Abstract: This paper is the result of mineral exploration engineering. Objective Vanadium is widely used in multiple fields due to its unique physical and chemical properties, playing an increasingly important role in economic development, and its demand is increasing. China is one of the countries with the largest amount of vanadium ore resources, ranking first in the world in terms of total resources, mineral product production, and consumption. It is of theoretical and practical significance to summarize the metallogenic regularity and assess the potential of vanadium. Methods we evaluated the potential of vanadium resources in China based on systematically summarizing the metallogenic regularity and mineralization patterns of vanadium deposits. Results The sedimentary vanadium deposits related to the black rock series are the type of vanadium deposits with the highest proportion of identified resources in China. This type of deposits mainly distribute in the northern edges and southeastern part of the Yangtze block, the Qinling-Dabie orogenic belt, and the northern edge of the Tarim block. The black strata deposited under the influence of marine invasion, biological organic matter, and hot water are the most important elements for searching for this type of deposit. The next important deposit type is vanadium titanium magnetite type related to basic ultrabasic rocks. The mineralization mainly related to deep and large faults that cut the crust. The banded structure igneous rock belt is the most important element for searching for this type of deposit. We delineated 213 prediction areas, including 32 in class A, 85 in class B and 96 in class C. Conclusions The characteristics of vanadium resources in China are abundant resources, low grade, abundant co associated minerals, and complex mineral composition. The low level of mineral processing and smelting technology leads to a low level of comprehensive utilization of vanadium resources and significant waste of resources. In order to consolidate and cultivate the advantages of vanadium resources in China, we suggest as fellow:(1) Increase the investment in the exploration of magmatic- type V-deposits to ensure the production capacity demand of the existing V-industrial base. (2) Strengthen the research and development of sedimentary-type V ore processing and metallurgical technology, strengthen the scientific and technological research and development of high-grade vanadium products. Improve the efficient and high-end development and utilization of vanadium resources.
