巴克利稀土公司北领地项目冶金测试实现99%提取率

ASX上市公司巴克利稀土（Barkly Rare Earths）宣布，其位于澳大利亚北领地的巴克利项目单阶段冶金测试取得重大突破1。该测试由珀斯独立实验室Nagrom完成，采用碱性转化和盐酸浸出工艺，成功实现了99%的镁铁稀土氧化物（MREO）提取率1，相比传统浸出方法的74%提取率实现了显著跃升1。

此外，该工艺还分别提取了94%的钇和92%的磷杂质分离率1。巴克利项目当前已探明推断矿资源4000万吨，品位为710 ppm MREO，包含82,000吨稀土氧化物（TREO）1。这些测试数据仅基于46个钻孔和755米的取样深度1。公司已任命MinPro Consult的Lu Zhang担任独立顾问1，并计划实施10,000米钻探活动1。

巴克利稀土在今年1月完成了一次800万澳元的超额认购首次公开募股1。该成果发布之际，澳大利亚政府最近承诺投入12亿澳元用于关键矿物战略储备1。

ASX-listed Barkly Rare Earths has announced a major breakthrough in processing rare earth minerals, achieving a 99% extraction rate for magnesium rare earth oxides (MREO) in single-stage metallurgical testing at its Barkly project in Australia's Northern Territory 1. This result represents a significant advance over the previous conventional leaching rate of 74% 1.

The achievement was delivered through alkaline conversion and hydrochloric acid leaching tests conducted independently by Perth-based Nagrom 1. The testing also successfully extracted 94% of yttrium and separated 92% of phosphorus impurities 1. The company is currently working with 40 million tonnes of inferred mineral resources at the Barkly project, grading 710 ppm MREO and containing 82,000 tonnes of total rare earth oxides (TREO), based on 46 drill holes and 755 metres of testing 1.

Building on these results, Barkly Rare Earths plans to conduct 10,000 metres of drilling activity and has appointed Lu Zhang of MinPro Consult as an independent advisor 1. The company raised $8 million in an oversubscribed initial public offering in January this year 1, positioning it to advance development of the project at a time when Australia's government has recently committed $1.2 billion to a critical minerals strategic reserve 1.
