Bauxite serves as a crucial raw material for the production of aluminum.However,China’s domestic bauxite resources have long been insufficient to satisfy the country’s demand.Consequently,it has beome imperative to import substantial quantities of high-quality bauxite from international sources to fulfill domestic requirements.The international trade dynamics of bauxite are continually evolving,influenced by economic policies and various other factors.Drawing upon the global bauxite trade volumes from 2012 to 2022,this paper employs complex network analysis to construct boths to chastic and weighted networks of bauxite trade.It examines the evolution of the global bauxite trade patterns,the changing status of major trading nations,and the specific characteristics of China’s bauxite trade network.The findings indicate that the scale of the global bauxite trade network demonstrates robustness.However,the network’s structure is asymmetrical,with trade connections between countries being relatively dispersed.The global bauxite trade exhibits significant frag-mentation.Among the nations engaged in bauxite trading,Australia and China,demonstrate the highest levels of import and export activity.However,their intermediary control capabilities require enhancement.Conversely,India possesses relatively robust intermediary control capabilities,effectively functioning as a “bridge” within the trade network.China stands as the world’s largest importer of bauxite,with an increasing prominence in export trade volume and a relatively concentrated market structure for both imports and exports.In the future,China is poised to broaden its bauxite import market framework,with a diverse array of potential sources.On one hand,China can augment its import share from established trading partners,including Australia,Indonesia,Brazil,and Guyana.On the other hand,China can leverage its geographical advantages to procure bauxite from Turkey,India,and other nations along the “Belt and Road Initiative”.

贵州铜仁又有2个勘查区块发现富厚锰矿体
据9月5日报道,贵州铜仁市锰矿勘查进展顺利,部分区块已见富厚碳酸锰矿体,预计可新增锰矿资源量5 000万t,全市锰矿资源量2024年底可新增至8亿t以上。
2024年以来,铜仁市建立5 000万元“富矿精开”专项发展资金,集中优势力量推进“152工程”,先后实施了松桃自治县杨家山锰矿普查、新民锰矿普查、耿溪锰矿详查,以及德江县金山萤石矿普查等地质找矿项目,进一步探明了锰矿和萤石矿等一批战略性矿产资源储量。
锰矿,是工业生产必需的基础性大宗矿产,是钢铁产业的重要支撑,更是新能源和新材料等新兴产业发展的重要原料。铜仁市积极争取省级地勘基金支持,2024年获批找矿项目5个,项目资金3 257万元。同时,进一步解放思想、创新举措,鼓励和支持社会资本参与找矿行动,撬动社会资本3 000万元实施松桃自治县耿溪锰矿详查项目。目前,全市3个区块锰矿勘查进展顺利,其中,松桃自治县杨家山锰矿普查项目已完成总钻探进尺1 056 m,新民锰矿普查项目已完成总钻探进尺2 587 m,耿溪锰矿详查项目已完成总钻探进尺4 254 m。新民区块和耿溪区块已见富厚碳酸锰矿体,预计可新增锰矿资源量5 000万t。找矿技术方面,铜仁市配合建立了隐伏喷溢沉积型锰矿找矿勘查理论体系,研发了立体探测与深部找矿关键技术,解决了找矿预测与绿色高效勘查难题,“隐伏超大型喷溢沉积型锰矿找矿勘查理论技术体系与工程应用”荣获2023年度国家科学技术进步奖二等奖。在此理论技术体系支撑下,该市松桃自治县耿溪锰矿详查项目首钻告捷,实际见矿情况与预测平均厚度4.5 m基本一致。铜仁市在省内率先开展固体矿产数字勘查,推进地质工作与大数据融合发展,实现了地质勘查全过程数字化。下一步,铜仁市将紧紧围绕贵州省委、省政府关于推进“富矿精开”总体要求,紧扣“精确探矿、精准配矿、精细开矿、精深用矿”4个关键环节,全力以赴打造全国唯一的世界级锰资源供应基地和金属锰国家级战略物资储备基地,不断强化科技创新和成果转化,加大基础地质调查力度,努力提升锰矿等矿产资源的找矿综合能力,为构建富有铜仁特色的现代化产业体系提供强有力支撑。
