作为高新科技发展的关键原材料，我国镓锗铟等稀散金属开发利用取得一系列重大突破。

自然资源部11月26日发布创新成果显示，我国已经攻克煤铝铜铅锌矿中低品位稀散金属高效提取技术，煤中锗综合回收率由55%提高至80%以上，铅锌冶炼过程镓锗铟综合回收率平均提高10%左右，铜冶炼过程硒碲铼回收率分别由93%、65%、70%提高至97%、90%和80%。

稀散金属高纯产品制备关键技术及核心装备也取得重要突破。我国自主研制出温度梯度冷凝—晶向控制定向结晶器等5种核心装备，实现半导体分子束外延8N级高纯镓批量稳定生产;开发出第一颗国产平面型高纯锗探测器，填补国内空白;建成超高纯锗等高端原材生产线，实现初级产品向高端产品的跨越;打破国外对高端产品垄断和限制，支撑MBE高纯镓、LCD面板铟、锗单晶衬底、碲化镉薄膜等关键战略金属产品自给率提升至70%以上，在国防、新能源、5G通讯、半导体等领域起到关键支撑作用。

据介绍，镓锗铟等稀散金属对战略性新兴产业、未来产业和国防军工等行业具有不可替代的基础支撑作用，是抢占科技制高点的关键原材料，对提升相关产业链供应链韧性和安全水平至关重要。我国稀散金属主要伴生在煤铝铜铅锌钼等矿物中，但长期以来，采选冶流程长、回收率低及高纯产品质量不稳定、成品率低。这一系列重大突破，有助于结束我国高端原材料和高精尖产品受制于人局面。
