高品位稀土精矿提取成功美国豪莱克溪项目潜力凸显

据外网报道，美洲稀土公司(ARE)在怀俄明州东南部的豪莱克溪项目取得重要进展，其矿石首次提取出高品位轻重稀土氧化物精矿，轻稀土精矿中稀土氧化物品位96.4%，重稀土氧化物精矿品位97.1%，且获第三方验证，表明该矿床能生产相关氧化物，可用于永磁生产。这一提取工作是美国国防部高级研究计划局“SynBREE”项目的一部分，由肯塔基大学等合作完成，专注于生物开采稀土元素。

豪莱克溪是美国矿石量最大的稀土项目之一，ARE将其第一阶段工程“牛仔州矿山”定位为美国磁体生产商的原料来源。目前美国多家公司计划建设总计1.5万吨的磁体生产能力，对应每年约需4800吨镨钕和600吨镝铽，而“牛仔州矿山”基准情形为年产镨钕1833吨、镝98吨、铽24吨。

该项目虽处于预可行性研究阶段，但正加快开发，包括完成工艺优化、公布预可行性研究、提交开采申请等。其符合JORC标准的探明和推定矿石资源量14.8亿吨，推测矿石资源量11.4亿吨。2025年更新的概略研究显示，初步建设投资4.56亿美元，按10%折现率，税后净现值5.58亿美元，内部收益率24%，且有相关借贷意向和资助支持。

此外，稀土磁体需求增长迅速，预计未来占比和需求量大幅上升，全球供应短缺可能加剧，而豪莱克溪项目有望为美国本土稀土供应做出贡献。美国目前唯一在产的稀土矿山是芒廷帕斯材料公司在加利福尼亚州的项目，该公司已在德克萨斯州建成相关生产设施。
