Red Metal Limited （ASX: RDM）宣布，位于伊萨山西南20公里处的Sybella稀土矿在低成本加工潜力方面取得重大进展。对Kary地区东部的空气芯和RC冲击钻屑样品进行的pH优化浸出试验表明，使用pH值在2.0至2.5之间的较弱且成本较低的硫酸，可以获得较好的磁性稀土氧化物（MREO）萃取效果。该公司的研究还发现了一种潜在的低成本堆内途径，可以从浸出液中去除铁杂质。

这些发现验证并显著改进了过去的结果，为最近钻探的金刚石岩心样品的最终柱浸出测试建立了明确的pH设定值。浸出数据有力地支持了堆浸处理在Kary带风化花岗岩矿石中提取MREO的应用。

具体而言，pH为2.0时，大部分风化Kary带矿石的钕、镨萃取率在76% ~ 81%之间，铽萃取率平均为43% ~ 60%，镝萃取率为38% ~ 55%。硫酸消耗量低，从17到22公斤/吨不等，铝杂质提取率低（3-6%），铁杂质提取率极低（1-2%）。

研究还表明，随着时间的推移，中和浸出液的pH值会导致氧化铁的沉淀和铁杂质的逐步减少。这种氧化铁沉淀反应产生酸，允许在减少酸添加的同时保持MREO萃取。

总经理Rob Rutherford表示，这些优化的浸出测试表明，在较弱的酸强度下，稀土的提取率很高，提高了该矿床的经济潜力。柱式浸出测试工作预计将在未来几个月内开始，以模拟堆浸出环境，提供碎石的最终数据。

此外，地质测绘扩大了Kary带的解释表面积，潜在地增加了其近地表潜力。计划开展进一步的测试工作，包括柱浸出测试和额外的间歇性瓶滚测试。
