西澳大利亚矿业公司Magnetic Resource NL（ASX：MAU）今日宣布，其100%持有的Lady Julie金矿项目（LJGP）最新冶金测试取得积极成果。 测试针对Lady Julie North 4（LJN4）矿床的7个冶金组合样品展开，结果表明重力富集与氰化浸出工艺相比浮选工艺更具可行性。
整体黄金回收率范围为70.9%至97.8%，平均值达92.0%，优于此前公布的浮选工艺平均回收率91.7%。 关键发现显示，在碳浸出（CIL）尾矿中增加Knelson重选机和20微米再磨工序后，黄金整体回收率从86.7%提升至92.0%，增幅达5.3%。
这一改进使公司能够考虑用额外的Knelson重选机替代浮选和强化浸出工艺，从而有望降低资本支出（CAPEX）、运营成本（OPEX）及操作复杂度。 Magnetic Resource总经理George Sakalidis表示：「Lady Julie金矿项目的可行性研究已证明这是澳大利亚最高边际收益的未开发金矿项目之一。此次优化工作的积极成果进一步降低了项目成本、执行风险，并提升了运营确定性。」
Lady Julie金矿项目位于西澳大利亚东部金矿带，是Magnetic Resource的核心资产。该项目资源量持续增长，目前已超过220万盎司，且仍在勘探扩展中。随着采矿许可的获得和冶金流程的优化，项目向商业化生产迈出了重要一步。
