近日，国家电投集团贵州遵义产业发展有限公司(以下简称“遵义公司”)牵头实施的省级科研项目《提高铝土矿焙烧脱硫能力的研究及应用》，顺利通过贵州省科技厅组织的验收评审并获颁验收证书。该项目研发的“悬浮态焙烧脱硫”核心技术，不仅破解了高硫铝土矿工业化利用的行业困局，更为我国铝工业资源保障体系建设提供了关键支撑，对推动有色金属行业高质量发展具有深远的战略意义。

作为务正道煤电铝循环经济产业园区的核心企业，遵义公司长期直面贵州铝土矿“高硫低品”的资源禀赋难题。数据显示，贵州铝土矿储量超11亿吨，但近八成硫含量超过2%，因传统工艺处理成本高、脱硫效果差，这些资源长期被视为“鸡肋矿”而闲置，与此同时我国铝土矿对外依存度曾高达56%，行业发展深陷“本土资源难用、优质矿依赖进口”的双重困境。

此次通过验收的“悬浮态焙烧脱硫”工艺，首次实现高硫铝土矿工业化规模应用的技术突破。该工艺通过精准控制焙烧温度与气流状态，将铝土矿中的总硫含量从2%以上稳定降至0.5%以下，完全满足氧化铝生产的原料标准。与传统湿法脱硫工艺相比，单吨矿石处理成本降低70-80元，目前已实现日均处理铝土矿6500吨的规模化生产能力，2024年依托该技术实现氧化铝产量88万吨，创造工业产值31亿元。

技术突破带来的不仅是成本优势，更激活了沉睡的矿产资源。据遵义公司生产技术部负责人吴忠辉介绍，该工艺有效盘活了务正道区域大量闲置的高硫铝土矿资源，使原本堆存占地、存在环保隐患的“问题矿”转化为工业“黄金矿”。这一转变不仅极大缓解了我国低硫铝土矿资源匮乏的压力，更打破了铝工业对进口高品位矿的长期依赖，为国内铝资源供应链构建起稳定的“本土屏障”。

在资源综合利用方面，该项目更构建起“变废为宝”的产业生态。遵义公司通过工艺耦合，将氧化铝生产过程中产生的种分母液输送至配套企业提取金属镓——这种被誉为“电子工业维生素”的稀缺资源，目前已实现单日100公斤的稳定产出，2024年累计产量达22吨，创造产值4300余万元。这种“采-冶-深加工”的全链条模式，使铝土矿资源价值得到“吃干榨尽”的最大化利用，成为贵州省“富矿精开”战略的典型实践。

“这项技术是产学研协同攻关的结晶，更是公司坚持科技创新驱动产业升级的缩影。”遵义公司党委副书记、总经理柴洪云表示，该项目的成功离不开与贵阳铝镁设计研究院、西安建筑科技大学等科研单位的深度合作。下一步，公司计划进一步扩大技术应用范围，2025年将完成工艺升级，实现5大类不同品位矿石的适配处理，支撑百万吨级氧化铝产能建设;同时深化金属镓、碳酸钾等延伸产业布局，推动铝产业链向高附加值领域延伸。

作为区域工业发展的“新引擎”，遵义公司的技术突破已带动务正道园区形成产业聚合效应。2024年，园区依托氧化铝主导产业实现产值37亿元，占务川县域工业总产值的90%。未来，随着技术成果的广泛转化，将为地方经济发展和我国铝工业绿色转型注入更强劲的动力。
